Question

Hiii!! I know for the most part that i should sketch a picture out, but i don’t remember the process may someone help me, would be greatly appreciated !!

Answer 1

22°

Explanation:

Okay, to first find the missing side, you need to use a² +b² = c²

getting 21.54 for the hypotenuse. From there, you're going to divide the leg (8) that's opposite of the angle you're trying to find and divide it by the hypotenuse (21.54). Then on you're caluclator you should have a button that says "Sin-1". You're going to use that and plug in the answer you got from 8/21.54. This'll give you your answer!

Answer 2

66

Explanation:

Find the last side of the triangle using the Pythagorean theorem.

`c^(2) = a^(2) + b^(2) \\20^(2) = 8^(2) + b^(2)`

B=
`4√(21)`

This makes b = 18.3

Now you can find the angle B = arcsin (opp/hyp)

B=arcsin
`(4√(21) )/(20)`

B= 66.42
