Question

The legs of a right triangle are 10 and 12. What is the length of the hypotenuse in simplest radical form?

A. 2√61
B. 4√17
C. 3√7
D. 5√13

Answer 1

The correct answer it’s A

Answer 2

2 * sqrt(61)

Explanation:

a = 10

b = 12

c = ?

c^2 = a^2 + b^2

c^2 = 10^2 + 12^2

c^2 = 100 + 144

c^2 = 244

c^2 = 4 * 61

sqrt(c^2) = sqrt(4) * sqrt(61)

c = 2 * sqrt(61)
