The special right triangle formula indicates that we get;

x = 4, y = 4·√3, z = 4·√6

The lengths of the sides of the triangle are found as follows;

The values of x, y, and z can be found using the side lengths, angles and trigonometric ratios of cosines sines and tangents as follows;

cos(60°) = x/8

x = 8 × cos(60°)

x = 4

Let h represent the height of the small right triangle we get;

sin(60°) = h/8

h = 8 × sin(60°)

8 × sin(60°) = 8 × √3/2

8 × √3/2 = 4·√3

h = 4·√3

The special 45° right triangle indicates that h = y

Therefore, y = 4·√3

sin(45°) = h/z

z = (4·√3)/sin(45°)

z = (4·√3)/(√2/2)

(4·√3)/(√2/2) = (4·√3) × (2/√2)

(4·√3) × (2/√2) = (8·√3)/√2

(8·√3)/√2 = (8·√3)/√2 × (√2/√2)

(8·√3)/√2 × (√2/√2) = 4·√6

z = 4·√6
