Question

One angle of equilateral triangle is 5x+30° then what is the others

Answer 1

In equilateral ∆, all angles are equal.

•°•

Each angle = 5x + 30°

Now,

Sum of all angles = 180°

3 ( 5x + 30° ) = 180°

5x + 30° = 60°

5x = 30°

x = 6

Each angle = 5x + 30° = 5 ( 6 ) + 30° = 60°

Also,

We know that each angle in equilateral ∆ is equal to 60°.

Answer 2

since all the angles are equal in an equilateral triangle..

consider a triangle ABC
AB=BC=CA=5x+30°
because it's equilateral triangle

so..
5x+30°+5x+30°+5x+30°=180°
15x+90°=180°
15x=180°-90°
15x=90°
x=90°/15
x=6°
Hence..
AB=BC=CA=5x+30°=5 (6)+30°=60°
