Answer:
b
Step-by-step explanation:
because those two triangles are face to face
The angles are supplementary, meaning the add up to equal 180°. the straight "angle" RQT is a straight line.
TQS + RQS = 180
(6x + 20) + (2x + 4) = 180
combine the like terms
8x + 24 = 180
get x by itself, -24 both sides
8x = 180 - 24
8x = 156
x = 156/8
x = 19.5
now use x to find the degrees for each angle
TQS = 6(19.5) + 20
= 117 + 20
= 137°
RQS = 2(19.5) + 4
= 39 + 4
= 43°
