Answer:
D. is the answer
Step-by-step explanation:
the side lengths always have to be equal so 6+8 = 10 and 10 is equal to 10
that means it makes a right triangle
The answer to the equation is 15
53 54 55
Consecutive Integers are integers that go one after the other unless explained otherwise, so 53, 54 and 55 add up to 162.
