Question

this isosceles triangle has two sides of equal length, a, that are longer than the length of the base, b. the perimeter of the triangle is 15.7 centimeters. the equation 2a b = 15.7 models this information.if one of the longer sides is 6.3 centimeters, which equation can be used to find the length of the base?

Answer 1

To find the length of the base of the isosceles triangle, the equation 2ab = 15.7 can be used which is 1.24603 centimeters.

Step-by-step explanation:

To find the length of the base of the isosceles triangle, we need to rearrange the equation 2ab = 15.7 to solve for b.

Divide both sides of the equation by 2a, giving us b = 15.7 / (2a).

If one of the longer sides is 6.3 centimetres, we can substitute this value into the equation to find the length of the base.

b = 15.7 / (2 * 6.3)

= 15.7 / 12.6

= 1.24603 centimeters.

Answer 2

Step-by-step explanation:

the correct answer is 12.6 + b =1 5.7
