If ∠n and ∠p are supplementary angles, m∠N=(x+3)° and m∠P=(7x-15)° ,find m∠P.

132 degrees

Step-by-step explanation:

x+ 3+7x-15=180

8x -12 =180

8x = 168

x=21

7(21) -15

147-15

132

y=67.7 Degrees

Step-by-step explanation:

You're given the opposite and adjacent sides to angle Y, so we use Tan to find the angle:

Tan(y)= 100/41

We then inverse tan to isolate y

y=tan^-1 100/41

y=67.7 Degrees

Note: Use a calculate to find the final answer
