Answer:
Measure of angle B is 70°.
Step-by-step explanation:
From the given right triangle ABC,
Sin B = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{AC}{AB}[/tex]
= [tex]\frac{4.8}{5.1}[/tex]
B = [tex]\text{Sin}^{-1}(\frac{48}{51} )[/tex]
= [tex]\text{Sin}^{-1}(0.94118 )[/tex]
= 70.25
m∠B ≈ 70° [Nearest degree]
Therefor, measure of angle B is 70°.
