Answer:
it is 20
Step-by-step explanation:
5 * 20 = 100
100 - 10 = 90 which equals a angle in a right angle triangle
The area of the 3 trapezoid would be all equal because the formula of the area of the trapezoid is :
A = h (b1 + b2) / 2
since the length of the base are equal in all three trapezoid, then the angle is not part in the equation of the area so the angle of the trapezoid does not affect its area. so that is why all the three trapezoid have equal area even with different angles.

I know this is late but hope it helps!
Solution: 137 / 2 = 68.5
LMP is 11 degress more so 68.5 + 11 = 79.5
NMP is 11 degrees less so 68.5 - 11 = 57.5
