okay right

hypothenuse^2=5^2+x^2

SerikMB Group TitleBest ResponseYou've already chosen the best response.0
hypothenuse/sin(90)=x/sin(42)

okay gotcha!

or you can go directly, x/sin(42)=5/sin(9042)

u can also use Tan of 42 = x / 5.

in 2nd one you have hypotenuse = x, and base = 9. So which trig. ratio means base/hypotenuse?

i think its D ?

I think it would be easier if you use tan(42)=x/5 => x=5tan(42)
