its in order like u put it in THE SAME ORDER.

The value of ∠1 is 140°, ∠3 is 65° and ∠5 is 115° after using the values of angles given in the figure.

According to the question,

We have a figure where some of the angles are given and we have to find angles which are numbered from 1 to 5.

In solving this question, we need to keep in mind two things. First is that the angle made on a straight line is always 180° (this will be referred to as the former part). Second is that the exterior angle of a triangle is equal to the sum of the opposite interior angles of that triangle (it will be referred to as the latter part).

So, to find ∠1, we will use the latter part.

∠1 = 80°+60°

∠1 = 140°

Now, in order to find ∠2 we will use the former part (angle made on a straight line).

∠1 + ∠2 = 180°

140° + ∠2 = 180°

∠2 = (180-140)°

∠2 = 40°

Now, to find ∠3, we will use the latter part.

∠2 + ∠3 = 105° (105° is an exterior angle)

40° + ∠3 = 105°

∠3 = (105-40)°

∠3 = 65°

Now, to find ∠4,  we will use the former part.

∠4 + 105° = 180°

∠4 = (180-105)°

∠4 = 75°

Now, after looking at the figure, it can be clearly seen that ∠5 is an exterior angle.

So, we have:

∠5 = ∠4 + 40°

∠5 = 75° + 40°

∠5 = 115°

Hence, the value of ∠1 is 140°, ∠3 is 65° and ∠5 is 115°.

The gradient of a line perpendicular to a line with a gradient of −2/3 is 3/2.

Gradient of a line

The gradient of a line is defined as the change in the "y" coordinate with respect to the change in the "x" coordinate of that line. The gradient of a line is helpful to find the inclination or steepness of a line.

We know that,

The product of gradient of two lines perpendicular to each other is equal to -1.

Let the gradient of the other line be m.

Hence, according to the data given in the question, we can write,

The average distance that the airplane covered in three flights is 2036 kilometers, time in trip from Hongkong to Manila is 1.468 hours, time in trip from Singapore to Manila is 3.146 hours, time in trip from Korea to Manila is 3.422 hours.

Given the distance that an airplane covered in three different trips:

Hongkong-Manila: 1116 kilometers, Singapore-Manila: 2391 kilometers,

Korea-Manila: 2601 kilometers.

We are required to find the average distance traveled by the airplane in the three trips, the time it took in each trip if the speed of airplane is 760 km/h and the trip that took the longest time to travel.

Average distance that airplane travelled in the three trips=(1116+2391+2601)/3

=6108/3

=2036 kilometers

We know that speed=distance/time.

Time=Distance/speed

Time in trip from Hongkong to Manila=1116/760=1.468 hours

Time in trip from Singapore to Manila=2391/760=3.146 hours

Time in trip from Korea to Manila=2601/760=3.422 hours

We can observe that the trip from Korea to Manila took longest time to travel.

Hence the average distance that the airplane covered in three flights is 2036 kilometers, time in trip from Hongkong to Manila is 1.468 hours, time in trip from Singapore to Manila is 3.146 hours, time in trip from Korea to Manila is 3.422 hours and the trip from Korea to Manila took longest time to travel.

Annual Medical cost = 1269.86

monthly premium cost to Ronald for the Blue Shield plan = $48.48.

For all doctor office visits, prescriptions, and major medical charges, Ronald will be responsible for 35 percent and the insurance company will cover 65 percent of covered charges.

The annual deductible cost = $630.

Ronald decided to review his medical bills from the previous year to see what costs he had incurred and to help him evaluate his choices. He visited his general physician 6 times during the year at a cost = $105 for each visit.

He also spent $71 and $95 on two prescriptions during the year.

= (Monthly premium cost × 12) + Deductible cost + (Coinsurance percent × Coinsurance expenses)

The Frisbee following a parabolic path will take  8.5 seconds to hit the ground.

Given that:

h(t) = â€" 0.07t2 - 0.007t - 5

The given equation is the parabolic equation showing the path traced by the frisbee. from the equation

h = height from ground

t = time consumed in seconds

time it takes to hit the ground will be at h = 0.  we therefore solve as follows:

The slope of a line is equal to -8/3.

What is the slope of a line?

The ratio of the change in the y coordinate to the change in the x coordinate is known as a line's slope in mathematics. Y and X, respectively, stand for the net change in the y-coordinate and the net change in the x-coordinate.

Locate two locations along the chosen line and find their coordinates.

Find the y-coordinate difference between these two places (rise). Find the difference between the x-coordinates of these two points (run). Subtract the difference in y-coordinates from the difference in x-coordinates (rise/run or slope).

The slope is defined as the relationship between the rise, or vertical change, between two points and the change, or horizontal change, between the same two points.

Given that, coordinates are (2, 6) and (8, -10)

Answer: X= 50

Step-by-step explanation:

To be able to solve this, you must identify vertical angles, as well as a linear pair.

The angle next to the angle of 103 is in a linear pair. This means they both add up to 180.

180- 103 = 77. The angle that is next to the angle of 103 is 77.

You have two angles in a triangle. You can use the triangle sum theorem, which states that all angles of a triangle add up to 180.

180- (53+ 77)= the third angle

180- 130 = 50 (the third angle)

The third angle of the triangle is a vertical angle in relation to x. All vertical angles are equal. This means that x= 50°.

The perimeter of the figure measures 38 inches.

The perimeter will be equal to the sum of the measures of each side of the figure.

We can see that the bottom side measures 13 inches, and also does the top side (where the top side is "broken" into two parts).

Similarly, the right side measures 6 inches, and also does the left side, only that the left side is broken into two parts.

Then the perimeter of the figure is:

a) Option D, (39,43) could be the 99% confidence limit.

b) The determined minimum sample size is 166.

a) For a given sample size, the confidence interval is just the range of values including the real population mean. The confidence interval is interpreted as follows:

The real population mean are contained in around 95% of the estimated confidence intervals.

The breadth of the interval and the confidence level (including 95% or 99%) have a positive connection.

As the confidence level rises, the range of both the confidence interval expands, implying that the lower limit of the interval shrinks and the top bound of the interval expands.

Option B is the correct one among the available possibilities since it entirely follows the pattern. When compared to a 99% confidence interval, 33 should be less than 34, and 46 is more than 43.
