Question

find the value of x , if the angles of a triangle are (x-10°),(2x +10°),(6x).

Answer 1

Answer:

.......we know that sum of all the angles of a triangle is 180°..

X –10°+ 2x+10°+6x = 180°

9x = 180°

X = 180°/9

X = 20°

Answer 2

Step-by-step explanation:

(x-10°)+(2x+10°)+6x=180° 9x=180°=x=180/9=x=20° 1st angle=(x-10°)=20-10=10° 2nd angle=(2x+10°)=40+10=50° 3rd angle=6x=6×20=120°
