Question

measure of three angles of a triangle (4x+20)°(3x-12)°,(2x+10)°respectively.According to its angles, what type of triangle is it??.

Answer 1

Sum of all angles = 180°

4x + 20 + 3x -12 + 2x + 10 = 180°

9x -18 = 180°

x - 2 = 20

x = 22°

Answer 2

(4x+20) + (3x-12) + (2x+10) = 180
(Angle sum property of a triangle)
4x+20+3x-12+2x+10 = 180
9x + 18= 180
9x = 162
x = 18

Substituting the value of x in the given angles:
4x+20 = 92
3x-12 = 32
2x +10 = 46
since all angles are different the triangle is an scalene triangle.
Hope it helps!
