Hi um, is anyone able to help me with these real quick? Any help is much appreciated, thank you so much!!
Angle c is arcsin (3/5) (remember sin is opp/hyp) = 36.87 degrees
Similar here angle r = arcsin (30/40) = 48.59 degrees
We can use the arctangent here
arctan (3/4) = C ≈ 36.87°
Second one..we know the opposite side to R and the hypotenuse...so....we can use the arcsin
arcsin (30/40) = R ≈ 48.59°
