Question

What is the value of x? x= ??

Answer 1

Answer:

X=50

Step-by-step explanation:

Because the top and bottom angles are formed by 2 intersecting lines, we know that the angles are equivalent to each other via the vertical angle theorem. This allows us to set the following equation:

[2(x+10)]=(3x-30)

You would then distribute the 2 on the left side to get

2x+20=3x-30

Then, simply combine like terms.

20+30=3x-2x

Simplify.

50=x

The answer is therefore 50.
