Question

two angle of a triangle are equal and the thrid angle is greater than each one of them by 18 .find the angle
​

Answer 1

Let the two equal angles be x

Third angle is greater than 18⁰ so,

third angle is (x + 18⁰)

x + x + (x + 18⁰) = 180⁰ (Angles Sum Property Of Triangle)

2x + x + 18⁰ = 180⁰

3x = 180⁰ - 18⁰

3x = 162⁰

x = 162⁰/3

x = 54⁰

Therefore,

First Angle = x = 54⁰

Second Angle = x = 54⁰

Third Angle = x + 18⁰ = 54⁰ + 18⁰

= 72⁰
