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

i think is g(1)=-1.

hope that i can
