Find the value of x? A.45 B.22 C.82 D.56

fgiga [73]

Answer: B

Step-by-step explanation:

By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two opposite interior angles.

(2x+8)+(3x+5)=123 [combine like terms]

5x+13=123 [subtract both sides by 13]

5x=110 [divide both sides by 5]

x=22

Now, we know that the answer is B.
