It is 105 degrees because the area of a triangle always adds up to 180
Answer:
x = 19
Step-by-step explanation:
To find the value of x, you set the equations as equal to each other:

Then you simplify:

(2p + 7)(3p-9)
2p x 3p= 6p^2
2p x -9= -18p
7 x 3p=21p
7 x -9=-63
6p^2 - 18p + 21p - 63
6p^2 + 3p -63 is the answer.
