Question

Use the Pythagorean Theorem to find the length of the hypotenuse in a right triangle whose legs are 3 and 4.
A. 3
B. 5
C. 4
D. 2

Answer 1

that is the same as 3^2+4^2 = c^2, solve for c

Answer 2

a^2 + b^2 = c^2
3^2 + 4^2 = c^2
Solve for c.
9 + 16 = c^2
25 = c^2
√25 = c
5 = C
C = Hypotenuse
Hypotenuse = 5

Answer 3

5
