Question

Solve for p. Show your work!!

Answer 1

Answer:

8p+7p+90 =180 (sum of three angles of triangles)

15p= 180-90

15p=90

p=90/15

p= 6

Step-by-step explanation:

Answer 2

Answer:

p=6

Step-by-step explanation:

triangles add up to 180 degrees, and a right angle =90 degrees.

from there, we can do 180-90=90 degrees then do 90/15=6. p =6

(we divide by 15 because 7+8=15)

to check, we see if all angles add up to 180.

7×6=42 8×6=48 right angle=90

42+48+90=180
