Write and solve an equation to calculate the measure of arc PQ (I'm not sure if my equation is correct)

Write And Solve An Equation To Calculate The Measure Of Arc PQ Im Not Sure If My Equation Is Correct class=

Answer :

Solution

Step 1

Find x

mArcPQ = mArcRS (equal arcs)

(x+17)° = (4x+2)° ( equal arcs)

Bring like terms together

17 -2 = 4x-x

3x = 15

3x/3 = 15/3

x = 5

Step 2

Find mArcPQ= (x +17)°

Substitute x = 5 in the expression

mArcPQ = 5+17 = 22°
