Answer:

130°

Step-by-step explanation:

All the interior angles should add up to 540 degrees because it's a pentagon

∠T ≅∠S, so ∠T is also 115°

∠P and ∠R are both 90°

Add everything up and solve for ∠Q:

115 + 115 + 90 + 90 + m∠Q = 540

410 + m∠Q = 540

m∠Q = 130°

The answer is p = 5.

Here are the steps I did.

1. Simplify 8p + 10p - p - 8p + 5 to 9p + 5 ( 9p + 5 = 50)

2. Subtract 5 from both sides ( 9p = 50 - 5)

3. Simplify 50 - 5 to 45 ( 9p = 45)

4. Divide both sides by 9 ( 45/9)

5. Simplify 45/9 to 5 ( p = 5)
