The 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 ?
Accepted Solution
A:
Answer:Step-by-step explanation:Since the length of one of the longer sides, a, has been given to be 6.3, plug it into the equation.2(6.3) + b = 15.712.6 + b = 15.7b = 15.7 - 12.6b = 3.1
