Question

A right triangle has a hypotenuse with a length of 130 cm. One leg has a length of 100 cm. What is the length of the other leg of the triangle? A. 130 B. 6900 C. 85 D. 130

Answer 1

Use:
c2 = a2 + b2
130^2 = 100^2 + b2
16,900 = 10,000 + b2
6900 = b2
b = 83.1 so I guess C

Answer 2

theanswer to your question is (c) 95
