Answer:
X= 12.5,
For question A: Angle 1: 90, Angle 2: 60, Angle 3: 30, Angle 4: 32, Angle 5: 116, Angle 6: 32, Angle 7: 32, Angle 8: 90, Angle 9: 60
For question B: Angle 1: 90, Angle 2: 68, Angle 3: 130 Angle 4: 130 Angle 5: 60, Angle 6: 60, Angle 7: 130 Angle 8: 130
Explanation:
For x we can see that the 50 degree is congruent to the 4x, so by doing the equation 50=4x, we find it to be 12.5.
Meaning: 5x=62.5 and 2x=25 and 4x=50
And in a trapezoid the angles all equal 360, and the angles on the same side equal 180.
In the triangle all angles equal 180.
