Answer: Choice A) 56 degrees
Step-by-step explanation:
The two interior angles 55 and 6x+8 add to the exterior angle 14x-1; this exterior angle is not adjacent to the interior angles mentioned.
Refer to the Remote Interior Angle Theorem for more information.
So,
55+(6x+8) = 14x-1
6x+63 = 14x-1
6x-14x = -1-63
-8x = -64
x = -64/(-8)
x = 8
Then we can determine angle T
angle T = 6x+8 = 6*8+8 = 56 degrees
