@jmjswag12 I'm back. first step is to draw a triangle:

Vocaloid:

(if you're wondering where I got the side lengths, you can use Pythagorean theorem, but eventually you should memorize these lengths)

Vocaloid:

you can use these side proportions to figure out which answers are/aren't true for example, QR = xsqrt(3) and since PR = x, the first statement is true

Vocaloid:

if you'd like, you can try the problem and I'd be happy to check your answers
