Question

In the diagram, what is the measure, of

Answer 1

For this case we have that by definition, a flat angle is the space included in an intersection between two straight lines whose opening measures 180 degrees.

Now, according to the figure we have that from V to S there are 180 degrees, like this:

`5x + 25x + 30 = 180`

We add similar terms:

`30x + 30 = 180`

Subtracting 30 from both sides of the equation:

`30x = 150`

Divide by 30 on both sides of the equation:

`x = \frac {150} {30}\\x = 5`

Answer:

`x = 5`
