Question

The longest side of a right triangle has a length of 8 centimeters. The length of the shortest side is

3 centimeters. What is the length in centimeters of the third side of the right triangle?
O A. 5
OB. 55
C. 73
O D. 11

Answer 1

7.41 cm

Explanation:

Pythagoras theorem :

Hypotenuse side² = Adjacent side² + Opposite side²

8² = 3² + x²

64 = 9 + x²

x² = 64 - 9

x² = 55

x =
`√(55)`

Opposite side = Third side of right triangle = 7.41 cm
