Question

Find the value of x.

Answer 1

ITS 10! WOOP WOOP

Answer 2

this is equilateral triangle so all sides are equal so 3*(5x+10) = 360 then solve for x
15x+30=360 then 15x=330 and x = 330/15

Answer 3

The lines on all of the sides mean that they are all equal. This means it's an equilateral triangle. The angles must be equal too.

Since angles in a triangle add to 180 deg,
3(5x+10) = 180
15x+30 = 180
15x = 180-30
x=150/15
x=10deg

Answer 4

thanks!!

@anette Angles in a triangle add to 180 deg not 360 :)
