Answer 1

Im thinking the answer could be 40

Answer 2

Answer: 40º

Explanation:

To find angle c, not give 2 angles at least, we must use a trigonometric function. With respect to angle c, we can see that we have the opposite and adjacent sides.

The trigonometric function that relates opposite and adjacent sides is tangent.

`tan=(opposite)/(adjacent)`

`tan=(21)/(25)`

`tan^-^1=40`
