Hello!

To find cosine, use the formula cos = adjacent / hypotenuse.

According to angle B, adjacent of angle B is side A, and the hypotenuse is side c because the hypotenuse is always opposite the right angle.

Therefore, the cosine of angle B is a/c.

Answer:

25√2 ≈ 35.36 inches

Step-by-step explanation:

The Pythagorean theorem can be used to find the leg length for the given conditions. It tells you the relation between legs a, b, and hypotenuse c is ...

c² = a² +b²

If a=b, and c=50, this becomes ...

50² = a² +a²

1250 = a² . . . . divide by 2

25√2 = a . . . . take the square root

The length of each leg is 25√2 ≈ 35.36 inches.
