Question

Find the X if the vertical of a triangle are 2x,40,60Number 7.

Answer 1

We will assume that the question is referring to the angles of a triangle. The vertices are 2x, 40, and 60.

Then, we have that the internal angles of a triangle sum up to 180 (degrees). Then, we have:

`2x+40+60=180`

Then, we have that subtracting 100 to both sides of the equation:

`2x+100=180\Rightarrow2x+100-100=180-100\Rightarrow2x=180-100`

Dividing by 2 to both sides of the equation:

`(2x)/(2)=(80)/(2)\Rightarrow x=40`

Therefore, we have:

`2\cdot40+40+60=180`

Therefore, the value for x is equal to 40 (x = 40).
