Question 5(Multiple Choice Worth 4 points) The legs of a right triangle are 12 centimetres and 16 centimeters. What is the length of the hypotenuse? 15 centimeters 17 centimeters 20 centimeters 28 centimeters

Answer 1

For this type of question, you have to use the Pythagorean Theorem:

$a^{2} +b^{2} = c^{2}$

In the theorem, a and b are the legs. To find the length of the hypotenuse, you have to square the lengths of the two legs and add it together. Then, find the square root of the sum.

First square both numbers.

$a=12 \\ a^{2} = 12 \times 12 = 144$

$b = 16 \\b^{2} = 16 \times 16 = 256$

Now that you have the numbers, you need to add them.

$144+256=400$

Now you need to find the square root of 400 to find the length of the htypotenuse.

$\sqrt{400} = 20$

The length of the hypotenuse is 20 cm, which is the 3rd choice

a. 15 cm x

b. 17 cm x

c. 20 cm ✔

d. 28 cm x
