Question

if the three angles of a triange are (x+15°) (6x/5+6°) and (2x/3+30°) prove that the triange is equilateral triangle​

Answer 1

Step-by-step explanation:

if the angles are angles of triangle

then ,

sum of all the angles of a triangle = 180

( x+15) + (6x/5+6 ) +(2x/3+30)= 180

15x +225 +18x + 90 +10x +450 = 270

43x + 765 = 270

43x =270 - 765

43x = -505

x = -505/43

then

1st angle = x + 15 =-505/43 + 15 = -6930/ 43
