The Total solution for NCERT class 6-12
The angles of a triangle are arranged in ascending order of magnitude. Ifthe difference between two consecutive angles is 100, find the threeangles.
The difference betweentwo consecutive angles is 100 (given)
Let x, x + 100,x + 200 be the consecutive angles
x + x + 100 +x + 200 = 1800
3x + 300 =1800
3x = 1800–300
3x = 1500
or x = 500
Again,
x + 100 =500 + 100 = 600
x+200 =500 + 200 = 700
Answer: Three anglesare 500,600 and 700.
