Problema Solution
A right triangle has legs with lengths x units and 7 units. The hypotenuse has length x+1 units. Find the perimeter of the triangle
Answer provided by our tutors
The equation for finding the perimeter is:
P=x+7+x+1
but since we do not kniw x yet, we have to find another equation that can help us solve for x, which is the Pythagorean Theorem.
x2+72=(x+1)2
x2+49=x2+2x+1
x2-x2-2x=1-49
-2x=-48
x=-48/-2
x=24
Substitute this value to the formula for the perimeter.
P=24+7+24+1
P=56
