Question

two equal sides of a triangle are each 5 meters less than twice the third side. if the perimeter of the triangle is 55 meters, find the angles

Answer 1

Let the third side = x
Other two sides = 2x-5
Perimeter of triangle =55m
X+(2x-5) = 55
x +2x = 55+5
3x=60
x=20m
1st side = 35m
2nd side = 35m
3rd side = 20m
