Triangle A.
The angle is less that 90 degrees.
Answer:
x = 11
Step-by-step explanation:
The given angles would be alternate exterior angles and be congruent, thus
6x - 2 = 5x + 9 ( subtract 5x from both sides )
x - 2 = 9 ( add 2 to both sides )
x = 11
#1 cause the slope is 7 and the y-intercept is -2
