Answer:
135°
Step-by-step explanation:
In order to answer the question, we must assume that the black lines are parallel to each other.
The given angles (2, 8) are "same-side (consecutive) exterior" angles, so are supplementary.
∠2 +∠8 = 180°
15x +5x = 180°
x = 180°/20 = 9°
∠2 = 15x = 15(9°) = 135°
Angles 2 and 3 are vertical angles, so angle 3 has the same measure as angle 2.
∠3 = 135°
Answer:
170 that is the answer hope it's right
y '(3) = (22 - 11(9))/(2 + 9)^2 = -77/121 = -7/11 (this is the slope at x = 3)
y - 3 = -7/11(x - 3) (this is the answer)
