Question

In a right triangle, a and b are the lengths of the legs and c is the length of the hypotenuse. If a=21 miles and c=75 miles, what is b? If necessary, round to the nearest tenth.

Answer 1

C = 29.7

Explanation:

Remember to use a^2 + b^2 = c^2

21^2+ 21^2 = c^2

441 + 441 = c^2

882 = c^2

you square root both sides

c= 29.6984

Round it

C = 29.7
