Answer 4

are you asking me what the measures are or what the opposite/adjacent formula is for?

Answer 5

Sine Function:
sin(θ) = Opposite / Hypotenuse
Cosine Function:
cos(θ) = Adjacent / Hypotenuse
Tangent Function:
tan(θ) = Opposite / Adjacent

Answer 6

that is how the functions are calculated
you have a triangle that does not show measure of Hypotenuse, so you need to use the
Tan(20) = x/12

x = opposite of angle 35
12= adjacent to angle 35

Answer 7

sorry I meant angle 20 not 35

Answer 8

ok! i think i can solve from here!

Answer 9

thank you!
