If the perimeter and the other two sides of the triangle are 18a - 14, 10a + 1, and 5a - 10. Then the third side of the triangle is 3a - 5.
What is the triangle?
Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
A scalene triangle has a perimeter of 18a - 14.
One side is 10a + 1 and another side is 5a - 10.
Then the third side will be
The perimeter is the sum of all sides.
Let the x be the third side. Then we have
Perimeter = sum of all sides
18a - 14 = 10a + 1 + 5a - 10 + x
18a - 14 = 15a - 9 + x
x = 3a - 5
