Question

In the Special Right Triangle below, solve for the value of y. Y = _____ (keep your answer in simplest radical form)

Options
5
5√2
10
10√2

Answer 1

Value of Y = 5√2 units

Explanation:

Given:

Perpendicular = X

Base = Y

Hypotenuse = 10

Find:

Value of Y

Computation:

Cos θ = Base / Hypotenuse

Cos 45 = Y / 10

1/√2 = Y / 10

Value of Y = 5√2 units
