Answer:

\boxed{x=58} & \boxed{m \angle C = 60}

Step-by-step explanation:

You need to find x first in order to find the measure of angle C. To solve for x, we will use the fact that interior angles of a triangle have angle measurements that add up to 180 degrees.

Using this knowledge, we can create an equation where angles A, B, and C add up to equal 180.

  • A+B+C=180
  • (x+4)+(x)+(x+2)=180

Combine like terms on the left side of the equation.

  • 3x + 6 = 180

Subtract 6 from both sides of the equation.

  • 3x=174

Divide both sides of the equation by 3.

  • x=58

Now that you've found the value of x, you can use this value to plug into the expression for angle C.

  • C=x+2
  • C=(58)+2
  • C=60

Therefore, the final answer is:

x=58\  \text{and} \ m \angle C = 60

An 8- pound bag of apples costs $17.50.What is the unit price?
hammer [34]
To find the answer to this we will set up a proportion. Lets do it:- 

\frac{8}{17.50} = \frac{1}{x}

Now we will cross multiply:-

7.50 · 1 = 17.50

Next we will divide:-

17.50 ÷ 8 = x

x = 2.18

So, $2.18 per pound of apples.  

Hope I helped ya!!

Find the size of an angle which is five times its supplement ​
zavuch27 [327]

Two supplementary angles when addd together equal 180.


let one angle = x

The second angle is 5 times that so would be 5x


x + 5x = 180

Simplify:

6x = 180

Divide both sides by 6:

X = 30

One angle is 30, the second angle would be 150


The answer is 150

in triangle PQR the measure of angle R=90, QP=73, RQ=55, and PR=48. what is the value of the sine of angle P to the nearest Hund
alexandr402 [8]

Answer:

P ≈ 48.89°(nearest hundredth)

Step-by-step explanation:

The triangle PQR forms a right angle triangle since angle R is 90°. The triangle has an hypotenuse , adjacent and opposite side.

Using the SOHCAHTOA principle one can find the sine ratio of angle P. Let us designate where each side represent.

opposite side(QR) = 55

adjacent side(PR) = 48

hypotenuse(PQ) = 73

sin P = opposite/hypotenuse

sin P = 55/73

P = sin⁻¹ 55/73

P = sin⁻¹ 0.75342465753

P = 48.8879095605

P ≈ 48.89°(nearest hundredth)
