A triangle has angles that measure 54.6 and 17.8 . What equation can be used to find the value of the third angle in the triangle
Answer:
180=54,6+17,8+x(the third angle)
Step-by-step explanation:
The three angles in a triangle counted together always give 180 degrees. Therefore, you can use simple equation, in which you subtract the values of the two known angles from 180 (degrees) and the final number will be the value of thethird angle. In this case, it's
180-54,6-17,8=x
107,6=x
Answer:
I dont really know this one but I think it is x = (54.6 +17.8) ÷ 2. I donk know for sure tho.

Answer:
the ramp must be lowered
Step-by-step explanation:
Use the definition of the sine function to find the height of a ramp that is 8°.
Sine = Opposite/Hypotenuse
sin(8°) = height/8
height = 8×sin(8°) = 1.11
The height Nate's dad allows is 1.11 feet. At 1.5 feet, the ramp is too high.
The ramp must be lowered.

How do I calculate parts for a recipe?One part equals one teaspoon, one cup, or one ounce if you're measuring in those units. All other constituents are tested against one component, which serves as the fundamental measurement. When choosing the portion size, it's useful to take the size of the completed cocktail—along with the amount of ice required—into account.An equalized ratio is used to measure a part in liquid measurements or 1 part of alcohol.Although it's not always the ideal option for bars and restaurants, it is a simple method to make and scale cocktails. When assessing bar inventory data, standard pours should always be in correct volume.Calculations :

Let f(x) = lnx and g(x) = log₂x. for all 0 < x < 1, f(x) < g(x): True.
How to determine the corresponding output value for this function?In this scenario and exercise, we would determine the corresponding output value for the functions f(x) and g(x) under the given mathematical operation and independent variables.
When x = 1, the output value for f(x) based on the table of values is given by;
f(x) = lnx
f(1) = ln(1).
f(1) = 0.
When x = 2, the output value for f(x) based on the table of values is given by;
f(x) = lnx
f(2) = ln(2).
f(2) = 0.69314718
When x = 1, the output value for g(x) based on the table of values is given by;
g(x) = log₂x
g(1) = log₂(1)
g(1) = 0.
When x = 2, the output value for g(x) based on the table of values is given by;
g(x) = log₂x
g(2) = log₂(2)
g(2) = 1.
In this context, we can logically deduce that the function f(x) is less than function g(x) for all 0 < x < 1.

Solve the equation
0.20x + 0.68(120 - x) = 0.54(120)
Please show step by step, thank you
Answer:
x = 25
Step-by-step explanation:
.20x + .68(120 - x) = .54(120) (Distribute .68 to 120 and -x)
.20x + 81.6 - .68x = .54(120) (multiply .54 and 120)
.20x + 81.6 - .68x = 69.6 ( add .20x and -.68x)
-.48x + 81.6 = 69.6 ( subtract 81.6 on each side)
-.48x = -12 (divide -12 by -.48)
x = 25

A mix of solid and striped shirts are hanging on a store rack. Sixty percent of the shirts are solid. If there are 45 shirts, how many are striped?
I will be giving out brainlist if the answer you submitted was correct❤️.
Please answer correctly and don’t waste my points these were hard to earn :((
first question:
72 tickets were sold.
so... if 18 is 25%
18+18=36
then 36 would be 50%
36+36=72
so then 72 would be 100%
72*.25=18
second question:
27 striped shirts
60% of 45 is 27 so that means there are 27 solids, the remaining 18 are striped.

A killer whale weighs 4.6t. Convert the weight to pounds.
Solve the system of linear equations given below.
4x+y= -4
x+y=2
Answers
a. (2,4)
b. (-4,-5)
c. (-2,4)
d (-4,5)
Answer: C
Steps: 4x + y = -4, x + y = 2
Isolate the x for (x + y = 2): x = 2 - y
Plug the value of x into the other equation: 4(2 - y) + y = -4
Simplify: -4y + 8 + y = -4
Combine like variables (letters): -4y + y = -3y
So -3y + 8 = -4
Subtract eight from both sides: -3y + 8 - 8 = -4 - 8
-3y = -12
Divide both sides by negative three: -3y ÷ -3 = -12 ÷ -3
Simplify: y = 4
Plug the value of y into one of the original equations (I'll use x + y = 2):
So x + 4 = 2
Isolate the x variable: x = -2

Answer:
28.4707
Step-by-step explanation:
The equations of three lines are given below. Line 1: 3y=2x+5 Line 2: 4x-6y=8 Line 3: y=2/3 x-8For each pair of lines, determine whether they are parallel, perpendicular, or neither. Line 1 and Line 2: Parallel Perpendicular Neither Line 1 and Line 3: Parallel Perpendicular Neither Line 2 and Line 3: Parallel Perpendicular Neither
Line 1 and Line 2 are parallel.
Line 1 and Line 3 are parallel.
Line 2 and Line 3 are parallel.
All three pairs of lines are parallel.
The equations of the three lines are:
Line 1: 3y = 2x + 5
Line 2: 4x - 6y = 8
Line 3: y = (2/3)x - 8
To determine whether two lines are parallel, perpendicular, or neither, we need to compare their slopes.
For Line 1 and Line 2:
To find the slope of Line 1, we can rewrite the equation in slope-intercept form: y = (2/3)x + 5/3. The slope of Line 1 is 2/3.
To find the slope of Line 2, we can rewrite the equation in slope-intercept form: y = (4/6)x - 4/6. Simplifying, we get y = (2/3)x - 2/3. The slope of Line 2 is 2/3.
Since the slopes of Line 1 and Line 2 are equal (both 2/3), these lines are parallel.
For Line 1 and Line 3:
The slope of Line 1 is 2/3.
The slope of Line 3 is 2/3.
Again, the slopes are equal, so Line 1 and Line 3 are parallel.
For Line 2 and Line 3:
The slope of Line 2 is 2/3.
The slope of Line 3 is also 2/3.
Once again, the slopes are equal, so Line 2 and Line 3 are parallel.
