Hi I really need help with this question
Nady [450]
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.
