Find the unknown side length, x. Write your answer in simplest radical form.

A. 15
B. 5 square root of 10
C. 2 square root of 70
D. 4 square root of 37

Answer 1

In a right triangle its sides can go with a^2+b^2= c^2
Then a^2+ 8^2= 17^2. a=15 (missing side)
Now 5^2+ 15^2= x^2
250=x^2 ------> 5 square root of 10=x answer b
