Question

In ABC below, what is the measure of angle B? In particular, which option below gives an exact expression for mB and an approximation that is correct to the nearest tenth of a degree? Note: The triangle is not drawn to scale.

Answer 1

Answer:

$sin^{-1} (\frac{3}{4} )=48.6$ degrees

Step-by-step explanation:

To find the measure of angle B, decide which of the six trig functions will work.

I used sin because you only know the opposite side and the hypotenuse.

$sin^{-1} (\frac{3}{4} )=48.6$ degrees
