The measures of two sides of a triangle are given. If P is the perimeter, and P = 10x + 5y, find the measure of the third side.
1 answer:
The measure of the third side is 2x + 2y
A triangle can be described as a polygon with three sides. The sum of the angle in a triangle is 180 degrees.
<u><em>Types of triangles are: </em></u>
- right angled triangle
- scalene triangle
- equilateral triangle
- isosceles triangle
The perimeter of a triangle is the sum of its three sides
(3x + 4y) + (5x - y) + s = 10x + 5y
Add similar terms
8x +3y + s = 10x + 5y
Make s the subject of the formula
s = 2x + 2y
