Find the measure of each angle whose degree measure is represented in terms of x in the given triangle.

Please help :)

Step-by-step explanation:

That's barely readable!  Anyway the solution is:

7x + 7x +2 +5x +7 = 180 degrees

19x + 9 = 180 degrees

19x = 171 degrees

x = 9

So the angles are:

7x = 63 degrees

7x + 2 = 65

5x + 7 = 52

Double check:

Since ALL 3 triangle sides add up to 180:

63 + 65 + 52 = 180 degrees

Step-by-step explanation:

As seen from the figure:

Group 1: It consists of three closed figures each having six sides. So these are all hexagons.

Group 2: It consists of three closed figures each having four sides.

All four are quadrilaterals.

So we can say that group 1 consists of hexagons and group two consists of quadrilaterals.
