Question

If h = 85 cm and 1 = 36 cm, what is the length of g?

A. 77 cm
B.
92 cm
C
49 cm
D
75 cm

Answer 1

Answer:A

Explanation:

h=85 f=36

Since it is a right angled triangle we can apply Pythagoras principle to get g

g=√(h^2 - f^2)

g=√(85^2 - 36^2)

g=√(85x85 - 36x36)

g=√(7225 - 1296)

g=√(5929)

g=77
