Question

the three angles of a triangle measure 2 x minus 10 degree and X + 31 degree and 5 x + 7 degree find the value of x and hence all the angles of the triangle

Answer 1

here you go ☆☆

angles are :-

▪2x-10
▪x+31
▪5x+7

□we know,

sum of all angles of triangle = 180°

▪2x-10+x+31+5x+7 = 180°

▪8x - 28 = 180

▪8x = 180 + 28

▪8x = 208

▪X = 208/8

▪X = 26

now,

▪ 2×26 -10 => 42°

▪ 26 + 31 => 57°

▪ 5× 26 + 7 => 137°
