Question

Can u find all the angles plz?

Answer 1

1 = 88 2 = 42 3 = 113

Explanation:

2 is 42 because it is the opposite angle and then you subtract 42 and 50 from 180 to get 88 for #1 and you subtract 42 and 25 from 180 to get 113 for #3.

Answer 2

The two sides we know are O pposite (300) and A djacent (400).

SOHCAH TOA tells us we must use T angent.

Calculate Opposite/Adjacent = 300/400 = 0.75

Find the angle from your calculator using tan-1
