You find the answer through the Pythagorean theorem
a^2 + b^2 = c^2 a & b are the legs and c is the hypotenuse
a = 40
b = ?
c = 41
40^2 + b^2 = 41^2
1600 + b^2 = 1681
b^2 = 1681 - 1600
b^2 = 81
b = 9
the length of the other leg is 9

Answer:
9x-1
Step-by-step explanation:
The perimeter of the triangle is adding up all 3 sides.

All I have done is combine like terms.
If there is a... x = something, replace x with the number.
