The angles are alternate interior angles, and they are congruent. Therefore, we can set the values equal to each other and solve for x.
15x + 5 = 140
15x = 135
x = 9
Hope this helps!! :)
50 degrees because if you add up all the angles and subtracts from 180 you get 50
Answer:
(2p+9)^2
Step-by-step explanation:
We know this is a perfect square trinomial
a^2 +2ab +b^2 = (a+b)^2
a = 2p b = 9
a^2 = 4p^2
2ab = 2*2p*9 = 36p
b^2 = 81
Check
4p^2 +36p+81 = (2p+9)^2
