the sum of the expanded angle is 180⇒

Answer:
Step-by-step explanation:
180 = 7x +2 + 7x + 2 + 180 - (17x -23)
180 = 14x +4 + 180 -17x +23
180 = -3x +207
3x = 27
x = 9
The value of x=20
Step-by-step explanation:
We need to find the value of x
We are given a right angle which is equal to 90°
So, all three angles must sum to 90°
Our equation will be:

Solving and finding value of x

So, the value of x=20

Answer:
The correct answer would be...
c. 8(x + 4)(x - 7)
Hope this helps!
T(s(x)) = -5
Substitute the value in for x and evaluate = -2
