Question

100 PTS *MIDDLE SCHOOL 7th GRADE***** HELP PLEASE!

Answer 1

x=108 degrees

Explanation:

We know that since ST is a line, it equals a total of 180 degrees.

Let's write an equation:

`180=x+(2)/(3)x`

simplify

`180=(5)/(3) x`

divide both sides by 5/3

108=x

So, x=108 degrees.

Hope this helps! :)

Answer 2

Answer: x=108 degrees

Explanation:

Since ST is a straight line, it measures 180 degrees.

This means that

x+(2/3)x=18

The simplified version is 5x/3=180. Now, we multiply both sides by 3. The equation becomes 5x=540 you would divide 5 by both sides which is ultimately x=108.
