Question

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

Answer 1

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°
