Question

Find the measure of angle B (9x+2) (5x-4)

Answer 1

Answer:

119

Step-by-step explanation:

$due \: to \: Corresponding \: angles \\ (5x - 4) + (9x + 2) = 180 \\ 14x = 182 \\ x = 13 \\ \\ 9.13 + 2 = b \\ b = 119$

Answer 2

Answer:

In the given figure, we know that (angle B+angle C)=180°.

$(9x + 2) + (5x - 4) = 180 \\ 14x - 2 = 180 \\ 14x = 182 \\ \boxed{x = 13}$

Angle B = (9x+2) = (9×13+2) = (117+2) = 119°.
