Question

two angles of a triangle are equal and the third angle is greater than each one of them by 18 degree find the angles​

Answer 1

Answer:

Step-by-step explanation:2 Angles are equal that means the triangle is isosceles triangle.

x+x+x+18=180

3x+18=180

3x=180-18

3x=162

x=162/3

x=54

Therefore angles are

x=54

x=54

x+18=54+18=72

=54,54,72

Answer 2

Let the equal angles be x

Then the third angle = x + 18

Acc. to the Ques.

x + x + (x + 18) = 180                (A.S.P)

3x + 18 = 180

3x = 180 - 18

3x = 162

x = 162/3

x = 54

Same angles = x = 54 degrees

Different angle = x + 18

= 54 + 18

= 72 degrees
