1. The length of each leg of an isosceles right triangle is 13 cm. What is the length of the hypotenuse?

Step-by-step explanation:

For right triangles, we can use the Pythagorean theorem. This means that a2+b2 = c2. In this problem, a and b are the given side lengths of the triangle. This means that a=b=13. To solve this problem, we plug in 13 to the equation above and solve for c.  

132 + 132 = c2

169+169 = c2

338 = c2

square root(338) = c

c = 18.38

18.38

Step-by-step

13^2 +13^2=338

square root 338

=18.38

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

well if you have a decimal you have to line them up and make sure the you have everything   straight and then add or subtract some thing with   division and   multiplying so just like them up
