The answer to this problem would be 2.5.
The answer is 50625 because 5*3 is 15 and take that to the power of 4
To find the length of the side opposite the angle while knowing the hypotenuse we can use the sine function:
sin(53) = (side opposite angle of 53 degrees) / hypotenuse
sin(53) = x / 24
x = 24 sin(53)
x = 19.16
Hope that helped
