Question

4. You sketch a right triangle that has a

hypotenuse of 12 centimeters, and one leg
that is 7 centimeters. How many centimeters
Is the other leg?

Answer 1

√95 cm

Explanation:

To solve, you need to use the pythagorean theorem, or a^2 + b^2 = c^2

The hypotenuse is the c and let one leg be b. You can write:

a^2 + 7^2 = 12^2

a^2 + 49 = 144

Now, you need to solve for a:

a^2 = 144 - 49

a^2 = 95

a = √95 cm, or about 9.75cm
