If (20, -21) is a point on the terminal side of the angle "theta" in standard position, evaluate all SIX trig functions. pls help i’m failing ;)

Two corresponding sides of two similar triangles are 3cm and 5cm. the area of the first triangle is 12cm^2. what is the area of the second triangle?

1. if events a and b are non-overlapping events, how do you find the probability that one or the other occurs? 2. what does it mean if p(a or b) equals 1?

Ineed to know the ordered pairs for this equation i need the answer quick because it’s a timed test
