Okay, so one of the geometric theorems is that two of the inside angles equals the outside angle in a situation like this one.

So, set them equal:
2x+ 2 + 4x + 8 = 8x - 30

Combine like terms:
6x + 10 = 8x - 30

40 = 2x

x = 20

Find the value of x.<br> Round to the nearest tenth.
aev [14]

Answer:

  C ≈ 22.1°

Step-by-step explanation:

The law of cosines formula is given. Solving it for C, we find ...

  C = arccos((a^2 +b^2 -c^2)/(2ab))

where a and b are the sides adjacent to the angle.

Then we have ...

  C = arccos((14^2 +19^2 -8^2)/(2·14·19)) = arccos(493/532)

  C ≈ 22.1°

If you have a fair number of these to do, a spreadsheet is a useful tool. There are also triangle solver apps on the web or your local smart platform that will do this, too.
