Answer:
28°
Step-by-step explanation:
Look at the angle, directly across from it and in no way touching the angle is the side with length 7. This side is OPPOSITE from the angle. The longest side, length 15, is the HYPOTENUSE. The trig function that uses Opposite and Hypotenuse is the sine function.
sin x = 7/15
Inverse sine will give you the angle given that you know the ratio (you do, its 7/15) on a calculator it will look like sin with a negative 1 exponent. It has nothing to do with exponents. Or it could be labelled arcain, sometimes abbreviated asin.
sin ^-1 (7/15)
= 27.8 approximately equal to 28°
