Answer:
x = 5
Step-by-step explanation:
It can help a lot to draw a diagram, if one is not provided. There is no requirement that it be drawn to scale. It just needs to be able to show the given information.
Given angle QRS is exterior to the triangle. Its measure is the sum of the two given remote interior angles:
8x -9 = (3x -11) +(3x +12)
2x = 10 . . . . . . . add 9-6x and simplify
x = 5 . . . . . . divide by 2

Answer:
Angles in a triangle add up to 180.
ABG - x + 90 + ANGLE AGB = 180
Angles on a straight add up to 180.
CDE - 8x + ANGLE D + 3x = 180
Alterate angles - ATTACHMENT
ANGLE D = x
8x + x + 3x = 180
12x = 180
x = 180/12
<h2>x = 15</h2>
