The exterior angles of any polygon add to 360 degrees.
If we call the interior angles A,B,C,D,E that means
(180-A) + (180-B) + (180-C) + (180-D) + (180-E) = 360
5(180)-360 = A+B+C+D+E
A+B+C+D+E = 540 degrees
So we know the indicated interior angles add to 540.
90 + 148 + 3x + x+10 + 112 = 540
4x + 360 = 540
4x = 180
x = 45
Answer: Choice C: 45
Answer:
There is no function posted with this question, but slope means how steep a line is. The slope is also known as the average rate of change.
Step-by-step explanation:
Remember the laws of exponents:
Then:
Therefore:
D. 12°
80° + 5x = 140°
or, 5x = 140° - 80°
or, x = 60°/5
:. = 12° <em><u>Ans</u></em>
