Question

note: figure is not drawn to scale.
if e = 9 cm and f = 40 cm, what is the length of g?
a. 39 cm
b. 31 cm
c. 43 cm
d. 41 cm

Explanation:

Step1: Apply Pythagorean theorem

$$g^{2}=e^{2}+f^{2}$$

Step2: Substitute values

$$g^{2}=9^{2}+40^{2}=81 + 1600=1681$$

Step3: Solve for \(g\)

$$g=\sqrt{1681}=41$$

Answer:

D. 41 cm
