Answer: 76 degrees

In order to solve for the ? Angle you can use inverse tangent with our given sides
The original equation for inverse tangent is tan^(angle)=opposite/hypotenuse, so plug the values in, and isolate the angle by dividing tangent. Then solve on a calculator and let x=?; tan^-1(40/10) which is equal to 75.96375653 which is approximately 76 degrees

Inscribed angles equal half of their arc length. So <D+ <B = 180
substitute: x+24+x+10 = 180
solve: 2x + 34 = 180
2x= 146
x= 73
NOw find the measure of angle A:
<a = x + 15
<a = 73 + 15
<a = 88
Now to find <C
<C = 180- 88
<C = 92
Hope this helps!
