Question

Find the length of BC
A
с
51° 58
B

Answer 1

45.074

Explanation:

You can use the trigonometric function sin which is equal to opposite/hypotenuse. Since you are given the angle and the hypotenuse you can use that to solve for the value of BC

`sin(\theta) = (opposite)/(hypotenuse)\\\\sin(51) = (BC)/(58)\\sin(51) * 58 = BC\\0.7771 * 58 = BC\\45.074 \approx BC`
