Answer:

A. 30

Step-by-step explanation:

sin theta = opposite side / hypotenuse

sin B = 8/16

sin B = 1/2

Take the arcsin of each side

arcsin sin(B) = arcsin (1/2)

B = arcsin (1/2)

B = 30

Answer:

Measure of ∠B is 30°

Step-by-step explanation:

Given the figure, we have to find the measure of angle B.

By trigonometric ratios formula,

[tex]sin\theta=\frac{Perpendicular}{Hypotenuse}[/tex]

⇒ [tex]sin\angle B=\frac{AC}{AB}=\frac{8}{16}[/tex]

⇒ [tex]sin\angle B=\frac{1}{2}[/tex]

⇒ [tex]\angle B=sin^{-1}(\frac{1}{2})[/tex]

⇒ [tex]\angle B=30^{\circ}[/tex]

Hence, measure of ∠B is 30°
