Find the length of the hypotenuse by using either "sine" or "cosine".
Sine= Length of opposite side/ Hypotenuse
Cosine= Length of adjacent side/ Hypotenuse
In order to use one of these, it depends on which angle they give you other than 90 degrees.
Hope this helps!
Answer:
x = 4, y = 3
Step-by-step explanation:
Equating corresponding coordinates , gives
2x = 8 ( divide both sides by 2 )
x = 4
and
3y = 9 ( divide both sides by 3 )
y = 3
