Question

in an equilateral triangle, one of the angles are (4x-20 degree). Find x​

Answer 1

Answer:

since the triangle is equilateral

therefore 4x - 20 = 60

so x = 20

Explanation:

4x - 20= 60

4x =80

x = 20

Answer 2

Answer:

in an equilateral triangle all angles are equal and measure of each angle is 60

⇒4x-20=60°

⇒4x=80°

⇒x=20°

or

4x-20+4x-20+4x-20=180°  (asp)

12x-60=180

12x=240°

x= 20°
