Answer:

P = 25

Q = 133

R = 22

Step-by-step explanation:

x + 13 + 10x + 13 + 2x - 2 = 180 add x's

13x + 13 + 13 - 2 = 180 add number's on left

13x + 24 = 180 subtract 24 from both sides

13x = 156 divide both sides by 13

x = 12

x + 13 = 12 + 13 = 25

10x + 13= 10(12) + 13 = 133

2x -2 = 2(12) - 2 = 22

1. Which angles are adjacent angles?
irga5000 [103]

Answer:

1. Which angles are adjacent.

CBX and FBC

Step-by-step explanation:

Okay so an adjacent angle is two angles with a common side. This means angles CBX and FBC are adjacent because they have the common side of "BC/CB"

Answer

2. Find the sum of the interior angles of a nonagon

1,260

Step-by-step explanation:

A nonagon is a 9 sided polygon with angles of 140. It wants the sum of all the angles. Since it has 9 sides, it has 9 angles. Now you can add 140, 9 times, or do 140 x 9. This gets you 1,260.

Answer

3. The measure of angle 3 is 101. find the measure of angle 4.

79

Step-by-step explanation.

Okay so both angles are against the same intersecting line, this means their sum must be 180. All we have to do here is subtract 180 and 101. this gets us 79.

Answer

4. Find the measure of each interior angle of a regular polygon with 12 sides.

1800

Step-by-step explanation.

Okay so a 12 sided regular polygon is a dodecagon. This has 12 angles with the degree of 150. This means 150 x 12 just like the 2nd question about nonagons. So 150 x 12 is 1800

Now that i've showed you how to do the first 4 you can apply the rest of the information on your own for 5 and the rest of the test.
