Last question!

Just seeing why I’m getting these wrong

In a right triangle with a leg of 4 and a hypotenuse of 8, find the measure of all angles.
Correct answer: 30deg, 60deg, 90deg
How?

yes

sin 30 = 1/2 = 4/8

so the other leg is
sqrt (64-16) = sqrt(16*3) = 4 sqrt 3

sin 60 = sqrt3/2 = 4 sqrt 3 /8 :) by the way
