Question

the angles of an triangle are (x+40) , (x-10) and (x) . find
the angles of an triangle.

Answer 1

X+40+X -10+X=180
3x+30=180
3x=150
X=50........1st angle
X+40=90.......2nd angle
x-10=40.......3rd angle

Answer 2

Hey friend, Here is your answer-
Sum of angles of triangle is 180 degree.
Therefore, x+40 + x-10 + x =180
= 3x + 30 =180
= 3x = 180 - 30
3x = 150
x = 50.

x +40= 50 +40 = 90
x - 10= 50 -10 = 40
x = 50.
Therefore 50 ,40 and 90 are the angles of triangle.
Hope it will help you friend.
