Answer:
The answer is 30.
Step-by-step explanation:
All of those angles will add up to 360 degrees. Since 150 is the same as the angle across from it that means the other one is 150. Add those 2 together that gets 300. So what is left? It is 60. So divide 60 between those two angles and you get 30.

Answer:
l = 24ft
Step-by-step explanation:
A = lw
360 = (x + 9)(x)
360 = x^2 + 9x
0 = x^2 + 9x - 360
0 = (x + 24)(x - 15)
x ≠ -24 (length cannot be negative)
x = 15
l = 15 + 9
l = 24ft
