Answer:
105 degrees
Explanation:
Here ,
8x+17=9x+6(being alternate angles )
17-6=9x-8x
11= x
Again,
8x-17=8×11+17
Therefore 8x-17=105 degrees
9514 1404 393
A) 105°
The two marked angles are alternate interior angles, so are congruent.
8x +17 = 9x +6
11 = x
8x +17 = 8(11) +17 = 88 +17 = 105 . . . . degrees
The bolded angle is 105°.
