Answer:
AOB = 55°
BOC = 87°
COD = 130°
AOD = 88°
Step-by-step explanation:
AOB = a°
= 55°
BOC = b°
= 87°
COD = c°
= 130°
AOD = 360°-AOB-BOC-COD
= 360°- a° - b° - c°
= 360° - 55° - 87° - 130°
= 88°

To find co-terminal angles, add or subtract 2π. Make sure the denominator is the same as the original problem.
5π/7
<u>+ 14π/7</u>
19π/7
5π/7
<u>- 14π/7</u>
-9π/7

Answer:
4/3
Step-by-step explanation:
Moving from (-4, -9) to (5, 3), x (the 'run') increases by 9 from -4 to 5, and y (the 'rise') increases by 12 from -9 to +3. Thus, the slope of the line connecting the two points is
m = rise / run = 12/9 = 4/3
It may help to think of the change in x (9) as the horizontal leg of a right triangle and the change in y (12) as the vertical leg. Then
m = (vertical leg length) / (horizontal leg length) = 12/9 = 4/3
Simply take 4.4% of $3:
0.044 * 3 = 0.132
You would pay $0.13 tax on a $3 item.
Complementary angles add up to 90 degrees. So say that the two angles you have are x and y. If the angles are in a 1:2 ratio, you are basically splitting them up into 3 groups. So splitting the 90 degrees into 3 groups gets 30 degrees into each group. You only care about the smaller angle, which makes up one group, so the smaller angle is 30 degrees.
