Question

One angle of a triangle is 2 more than thrice of other angle. If the third angle is 38 degrees, then find angles of triangle

Answer 1

let the first angle =x

second angle = 2 more than thrice the

other angle

=3×x+2

=3x+2

Third angle. =38°

sum of the angles of triangle = 180°

X +3X+2+38°=180°

4x+40°=180°

4x=180°‐40°

4x=140°

x. =140/4

x=35°

First angle = x. =35°

second angle = 3x+2

=3×35+2

=105+2

=107°
