The legs of a right triangle can be represented by x and (x+2). the hypotenuse is 10 centimeters. find the length of each leg

6 cm and 8 cm

Step-by-step explanation:

Use Pythagorean theorem:

c² = a² + b²

10² = x² + (x+2)²

100 = x² + x² + 4x + 4

0 = 2x² + 4x − 96

0 = x² + 2x − 48

0 = (x − 6) (x + 8)

x = 6 or -8

x must be positive, so x = 6.  Which means x+2 = 8.

no, because the sides are not congruent

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
