Question

In ΔGHI, g = 53 inches, h = 93 inches and ∠I=91°. Find the length of i, to the nearest inch.

Answer 1

Answer:

108inches

Step-by-step explanation:

Using the cosine rule formula

i² = g²+h²-2ghcosI

Given g = 53inches

h = 93inches

∠I = 91°

Substituting the values in the equation

i² = 53²+93²-2(53)(93)cos91°

i² = 11,458-(-172.05)

i² = 11,458+172.05

i² = 11630.05

i = √11630.05

i = 107.84inches

I = 108inches (to nearest inches)
