Find the Missing Side Length of a Special Right Triangle

What are x and y in this 30-60-90 triangle?

• x = 6 y = 3√3

• x = 1.5√3 y =1.5

• x = 3√3 y = 6

• x = √3 y = 2√3

What are u and v in this 30-60-90 triangle?

• v = 2√3 u = 6

• v = 4 u = 4√3

• v = 4 u = 4√2

• v = 4√3 u = 8√3

Use the 45-45-90 theorem to solve for the hypotenuse.

• 16

• 8

• 8√2

• √16

Determine the value of x.

• x = 10√2

• x = 10

• x = 5√3

• x = 5√6

Determine the value of x.

• x = 8√2

• x = 16√2

• x = 16

• x = 8√6

Determine the value of c.

• c = 6√3

• c = 12√3

• c = 18

• c = 18√2

I have been given a hypotenuse in this 45-45-90 triangle.  How do I find the length of a leg of the triangle?

• Multiply by √2

• Divide by √2

• It's the same length as the hypotenuse.

• Divide by 2

I have been given the short leg in this 30-60-90 triangle.  How do I find the long leg?

• Multiply 4 by 2

• Multiply 4 by √3

• Multiply 4 by √2

• Divide 4 by 2

Find the missing side lengths.

• a = 4, b = 4

• a = 4, b = 2√2

• a = 2√2,  b = 4

• a = 4, b = 4

• a=√6   b=√2
• a=4   b=2
• a=√6   b=2
• a=2   b4
