Answer to Problem 18P
Required equation:
The length of each of two equal sides of an isosceles triangle is 17.5cm.
Explanation of Solution
Given information:
Triangle has two equal sides and the third side is 15cm.
Perimeter of the triangle is 50 cm.
Calculation:
Let the two of the equal sides =
Third side = 15 cm.
Perimeter of triangle = side1+side2+side3.
Substituting values of side1, side2 and side 3 in above formula, we get
Now, we need to solve it for x
Combine like terms
Subtract 15 on sides
Divide both sides by 2
Therefore, the length of each of two equal sides of an isosceles triangle is 17.5cm.
