Question

12)

Find the length of the hypotenuse on a right triangle if the other sides have lengths of 5 cm and 12 cm.
A) 7 cm
B) 13 cm
C) 17 cm
D) 169 cm

Answer 1

Using Pythagoras Theorem:-

h^2 = 5^2 + 12^2

h^2 = 25 + 144 = 169

h = sqrt 169

= 13 answer

Answer 2

Your answer is going to be Option B.

5² + 12² = c²

25 + 144 = c²

169 = c²

√(c²) = √169

c = +/- 13

Distance can't be negative so your answer is 13 cm
