If RTS is isosceles, find mS
Pls pls help!

Answer: {8, 2}

Step-by-step explanation: Move the -9 to the right side.

So we have (x - 5)² = 9.

Square rooting both sides, we have x - 5 = ± 3.

Always use plus or minus when square

rooting both sides of an equation.

So either x - 5 = 3 or x - 5 = -3.

Solving each equation from here, our solution is {8, 2}.

Answer:

x=-3

Step-by-step explanation:

Answer:

m∠1 = 140°

m∠2 = 40°

m∠3 = 65°

m∠4 = 75°

m∠5 = 115°

Step-by-step explanation:

We will use a few different methods to find the angles:

A triangle's angles will always add up to 180°. With this information, we can find the last angle of the triangle on the left:

∠1+∠2+∠3=180°

60+80+∠3=180°

Let x represent the value of ∠3. Simplify addition:

[tex]140+x=180[/tex]

Subtract 140 from both sides:

[tex]140-140+x=180-140\\\\x=40[/tex]

The unknown angle is 40°. With this information, we can find the

m∠1:

m∠1 and the 40° we just found are supplementary angles, which means that their measures will add up to a total of 180°.

∠1+∠2=180°

Insert the value we know:

40°+∠2=180

Let x represent the value of ∠2. Subtract 40 from both sides:

[tex]40-40+x=180-40\\\\x=140[/tex]

There fore:

m∠1=140°

We can use this same rule to find the m∠2:

∠1+∠2=180°

or, we can use the vertical angles rule. The first angle we found (Which is 40°) is a vertical angle to m∠2, so they have the same value. Therefore:

m∠2=40°

To find m∠3, we need to find the other missing angle in the middle triangle. Use the supplementary angle rule, since the missing angle is supplementary to the angle that is 105°:

∠1+∠2=180°

Insert the known values, substituting x for the unknown angle:

[tex]x+105=180[/tex]

Subtract 105 from both sides:

[tex]x+105-105=180-105\\\\x=75[/tex]

The unknown angle is 75°. Now find m∠3, knowing that triangles add up to 180°:

m∠2+m∠3+75=180

Insert the m∠2, make m∠3 be x:

[tex]40+x+75=180[/tex]

Simplify addition:

[tex]115+x=180[/tex]

Subtract 115 from both sides:

[tex]115-115+x=180-115\\\\x=65[/tex]

Therefore:

m∠3=65°

To find m∠4, use the vertical angle rule.

Therefore:

m∠4=75°

To find m∠5, we could find all triangle measures of the least triangle, or we can use the following:

An exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of exterior angle and interior angle is equal to 180 degrees.

The m∠5 is the exterior angle, and the opposite interior angles are 75° and 40°:

[tex]75+40=115[/tex]

Therefore:

m∠5=115°

Answer:

The answer is $16

Step-by-step explanation:

Venessa owed her friend $24. She paid back $8.

Account status = 8 - 24 = -$16

The amount remaining to pay to make account zero 24 - 8 = $16.

Answer:

The answer is D.) 16

Step-by-step explanation:

To solve this problem you are gonna do subtraction. What you are going to subtract is 24 - 8, because Vanessa took $24.00 from her friend and they want to you figure out how much she needs to pay back and in math when you are trying to figure out problems like this then you would use subtraction.

Answer:

0.9375 | 93.75%

Step-by-step explanation:

g o o g l e

for the percent times the decimal by 100 and for the decimal just divide the fraction by it self so 15 divided by 16

Answer:

0.9375

93/75%

Step-by-step explanation:

Perform the division:

15 / 16 = 0.9375

and then find the percent form by multiplying this result by 100:

0.9375 * 100 = 93.75%

Answer:

The length of s is 5.1 inches to the nearest tenth of an inch

Step-by-step explanation:

In Δ RST

∵ t is the opposite side to ∠T

∵ r is the opposite side to ∠R

∵ s is the opposite side to ∠S

→ To find s let us use the cosine rule

∴ s² = t² + r² - 2 × t × r × cos∠S

∵ t = 4.1 inches, r = 7.1 inches, and m∠S = 45°

→ Substitute them in the rule above

∴ s² = (4.1)² + (7.1)² - 2 × 4.1 × 7.1 × cos(45°)

∴ s² = 16.81 + 50.41 - 41.1677568

∴ s² = 26.0522432

→ Take √ for both sides

∴ s = 5.10413981

→ Round it to the nearest tenth

∴ s = 5.1 inches

∴ The length of s is 5.1 inches to the nearest tenth of an inch

Answer:

19-3=x

Step-by-step explanation:

The equation that represents the situation is x + 3 = 19.

And Ronald is 16 years old.

Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.

Given:

Ronald is x years old.

His friend Colin is 3 years older than Ronald.

That means,

the Collin age is x+3 years.

Colin is 19 years old.

Then the equation,

x + 3 = 19

x = 19 - 3

x = 16

Therefore, Ronald is 16 years old.
