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)
