Well we can’t see all the graphs
Since FE is 2, 2+9 = 11
GE is D) 11
Since it is as a ratio of 14:31 there has to be a factor of something. Let's assume this factor as x.
Therefore,
14x + 31x = 90
45x = 90
x = 2
So we have a factor of two. Plug x back into the equation.
The larger angle is 31 * 2 = 62 degrees.
