G)
Angles on a straight line add to 180°;
According to this rule, we can formulate the following equation:
(2x + 4) + (x + 8) = 180
Now, just simplify and solve for x:
3x + 12 = 180
3x = 168
x = 56°

H)
What is shown on the diagram are sometimes called C-angles;
They also add to 180°;
This C-angle rule is one of 3 that exist when you have a pair of parallel lines (in this case the two horizontal ones) and one line passing through them both.
Using the C-angle rule, we can formulate the equation:
(3x + 9) + (2x - 4) = 180
Simplify and solve:
5x + 5 = 180
5x = 175
x = 35°

What is the answer please help

Answer:

B: 22.5 degrees

Step-by-step explanation:

The interior angles of a pentagon add up to 540 degrees

(if you dont believe me you can turn a pentagon into three triangles, 3x180 = 540)

So you have four same angles say measure "x" degrees, and one final one that measures "5x" degrees, so 9x = 540, and x = 60

Unless I read the problem wrong, 60 degrees is the answer which is not an option :P

Edit: Yea I read it wrong, the final angle is 5 times the other four angles COMBINED, so that angle measures "20x" degrees.

The total would be 24x = 540, and so x = 22.5
