Find C and D using formula for special right triangles

Given:

Right triangles:

To find:

The value of c and value of d

Solution:

In the first right triangle:

θ = 45°

Opposite side to θ = 5

Hypotenuse = c

The value of sin 45° =

Do cross multiplication, we get

In the second right triangle:

θ = 60°

Opposite side to θ = 4

Adjacent side to θ = d

Do cross multiplication, we get

The value of and .

2 5/8 is the final answer! : )
