Question

WILL MARK BRAINLIEST solve for X

Answer 1

$x = 47$

Step-by-step explanation:

The 3rd interior angle of the triangle can be written as

$\angle{3} = 180 - 45 - x = 135 - x$

The angle above is supplementary to the angle (2x - 2), therefore

$(135 - x) + (2x - 2) = 180 \Rightarrow 133 + x = 180$

Solving for x, we get

$x = 47$
