Answer:
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
Answer:18.38
Step-by-step
13^2 +13^2=338
square root 338
=18.38
