Question

The angles of a triangle are 3x0, (2x+20) and (5x-4). Find the angles. Hence show that the triangle Is an equilateral triangle.

Answer 1

3X+2X+20+5X_4 IS THE ANS

Answer 2

Angles= 36, 44 and 100

Step-by-step explanation:

angle of the triangle= 3x, 2x+20 and 5x+40

according to angle sum property,

3x+2x+20+5x+40=180

10x+60=180

10x=120

x=120/10

x=12 degrees

angle 1 =3x = 3*12= 36 degrees

angle 2 = 2x+20 = 2*12+20 = 24+20 =44 degrees

angle 3 = 5x+40 = 5*12+40 = 60+40 = 100 degrees
