Question

Find the perimeter of a right triangle with a leg of 8 cm and a hypotenuse of 17 cm.

Answer 1

P = 43.78829

The equal sign will be squiggly lines. (I forget what they are called.

Answer 2

Answer:

40cm

Step-by-step explanation:

1. To find the missing leg, use the Pythagorean theorem a²+ b² = c² and substitute the numbers a² + 8² = 17².

2. So a = 15 since 17²-8² = 289 - 64 =225 and the square root of 225 is 15

3. Now that all the lengths have been found. So the perimeter of the right triangle is 40cm.
