Question

What is angle B.........

Answer 1

Answer:

64.62°

Step-by-step explanation:

Use good 'ol SOHCAHTOA. Since we know the hypotenuse and the adjacent values, we use cosine.

Therefore:

$cos( ?) = \frac{3}{7}$

Take the inverse cosine of each side:

${cos}^{ - 1} (cos( ?)) = {cos}^{ - 1} ( \frac{3}{7} )$

Inverse cosine of cosine cancel each other out:

$? = {cos}^{ - 1} ( \frac{3}{7} )$

Use a calculator:

$? = 64.623$

Therefore the angle is 64.62°

Answer 2

I believe it’s a 30 degree angle
