Question

Given that a and b are legs of a right triangle and c is the hypotenuse. Solve for the missing length using the Pythagorean Theorem.
a = 7 b = 9 c= ?

A. c= 130
B. c= 65
C. c=2 sqrt{65}
D c = c=s qrt{130}

Answer 1

Answer:

D

Step-by-step explanation:

a^2+b^2=c^2

7^2+9^2=C^2

49+81=c^2

$\sqrt{49+81}$=c

$\sqrt{130}$=c
