If the length of one leg of a right triangle is 4 and the hypotenuse is 65−−√ , what is the length of the other leg?

Question

A. 7
B. 3–√
C. 69−−√
D. 33−−√

Answer 1

a = length of one leg

b = length of the other leg

c = length of hypotenuse

 

You know a and c, so get b from

 

b = √(c² - a²)

 

Plug in the correct values of a and c.  (I cannot tell what you mean by the unconventional notation -√ and --√)
