Answer:
p = 5
Explanation:
Th angles are complimentary, meaning that they equal 90° if put together. This mean that you can set them equal to eachother.
3p + 10 = 5p
Subtract 3p from both sides.
10 = 2p
Divide both sides by 2.
p = 5
You can check you work by plugging in 5 for p.
3(5) + 10 = 5(5)
15 + 10 = 25
25 = 25
Therefore, p = 5.
Sorry if I'm wrong, but I hoped this helped. Have a great day/night!
