Question

In ΔABC, the measure of ∠C=90°, CA = 29 feet, and AB = 72 feet. Find the measure of ∠B to the nearest degree.

Answer 1

24

Explanation:

sinB=

hypotenuse

opposite

​

=

72

29

​

\sin B = \frac{29}{72}

sinB=

72

29

​

B=\sin^{-1}(\frac{29}{72})

B=sin

−1

B=23.752\approx 24^{\circ}

B=23.752≈24
