Using SOH CAH TOA to find the side of a right angle triangle

Say you have a triangle where you know an acute angle and the hypotenuse and you’re trying to find the opposite side. You would use Sin. (SOH Sin Opposite Hypotenuse)

Ex. Sin 39 = x/9

(9)Sin39 = x/9(9)

x = 5.7

 

(39 = angle, x = opposite side, 9 Hypotenuse)
