The hypotenuse of a right triangle is 13ft long. The longer leg is 7ft longer than the shorter leg. Find the side lengths of the triangle.

The side lengths are 5, 12, 13

Step-by-step explanation:

These are the side lengths we know before we have solved the problem.

a= x   b= x+7   c= 13

If we put this into the Pythagorean theorem, we get

Expand

Subtract 169 from both sides

Solve using the quadratic formula

a= 2   b= 14   c= -120

If we separate the solutions we get

and

Since this is a question about length, we can ignore the negative.

So the longer leg is 12ft and the shorter leg is 5ft

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
