Answer 1

Answer:

17 cm

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean Theorem.

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

where a and b are the legs and c is the hypotenuse.

In this triangle, 8 cm and 15 cm are the legs, because they form the right angle. The hypotenuse is unknown.

a= 8

b= 15

$8^2 + 15^2= c^2$

Solve the exponents on the left side of the equation.

8^2= 8*8= 64

$64+15^2=c^2$

15^2= 15*15= 225

$64+225=c^2$

Add 64 and 225

$289=c^2$

c is being squared. We want to get c by itself, so we must perform the inverse. The inverse would be taking the square root.

Take the square root of both sides.

$\sqrt{289} =\sqrt{c^2}$

$\sqrt{289} =c$

$17=c$

c= 17 cm

The length of the hypotenuse is 17 centimeters.

Answer 2

Answer:

The hypotenuse is 17

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

8^2 + 15^2 = c^2

64 + 225 = c^2

289 = c^2

Take the square root of each side

sqrt(289) = sqrt(c^2)

17 = c
