Question

If angles of a triangle are (x-10°), (2x +10°) and 6x, then value of x is
(a)40°
(b) 30°
(c) 20°
(d) 90°​

Answer 1

Answer:

20 degrees

Step-by-step explanation:

As the angles of a triangle add up to 180 degrees,

x-10+2x+10+6x = 180

9x  = 180

So,

x = 180/9

  = 20 degrees

Answer 2

Answer:

the value of X =20° and 10°,50°and 120° are the angles of the given triangle
