Question

Find the cos of ∠W.
24
70
W
V
U
Simplify your answer and write it as a proper fraction, improper fraction, or whole number.
cos(W)=

Answer 1

I need a bit more info about which side(s) the numbers 24 and 70 label in the triangle (or a picture). Without that, there are two reasonable interpretations:

- If the triangle is right with legs 24 and 70, then the hypotenuse is sqrt(24^2+70^2)=74. For angle W:
- If the side opposite W has length 24, then an adjacent side is 70, so cos(W)=70/74 = 35/37.
- If the side opposite W has length 70, then an adjacent side is 24, so cos(W)=24/74 = 12/37.

Tell me which side is opposite angle W (or upload the diagram) and I will give the single correct simplified fraction.
