Answer 1

perhaps an equation involving trigonometric functions.. :)

Answer 2

what's the problem all about?

Answer 3

are you perhaps asked to find theta?

Answer 4

It says, "Find one solution for each equation. Assume that all angles in which an unknown appears are acute angles." I don't understand what it's asking at all.

Answer 5

Acute Angle an angle that is less than 90°
Right Angle an angle that is 90° exactly
Obtuse Angle an angle that is greater than 90° but
less than 180°

Answer 6

@Sweet-T22 pls examine it. ask me if you can't understand the solution

Answer 7

I think I got it. Can I do one on here and you tell me whether I am correct or not...?

Answer 8
