Question

The vertical angle of an isocless triangle is 18 degree more than the base angle. Find each angle of the triangle

Answer 1

Step-by-step explanation:

let the angles opposite to equal sides are each equal to x degree.

By Angle Sum Property of Triangle

x + x + 18 degrees =180 degrees

so , 2x + 18 = 180 degrees

2x = 180 -18 degrees

x = 162 ÷2

x =81 degrees

so the three angles are 18 degrees , 81 degrees and 81 degrees.
