Answer
3.2
Step-by-step explanation
8% of 40 is 3.2
so it would be 40- 3.2 and that = 36.8
Answer:
Step-by-step explanation:
By the polygon exterior angle sum theorem, all the exterior angles of a polygon add up to equal 360 regardless of the number of sides it has. That means that 82 + 150 + b = 360 so
b + 232 = 360 and
b = 128
10 of them fail so 10 of them get 0 and no points to there GPA
5 divided by -25 is -0.2
-25 divided by 5 is -5
Answer:
<em>x = 15°</em>
<em>x = 135°</em>
<em>x = -45°</em>
<em>x = -180°</em>
Step-by-step explanation:
<u>Trigonometric Equations</u>
Solve
cos(2x + 30°) = 0.5 for -180° ≤ x ≤ 180°
Applying the inverse cosine function:
2x + 30° = arccos(0.5)
There are several angles whose cosine is 0.5. They are 60°, 300°, -60° and -300°, thus we have these candidate solutions:
2x + 30° = 60°
2x + 30° = 300°
2x + 30° = -60°
2x + 30° = -300°
Subtracting 30° to all the equations:
2x = 60° - 30° = 30°
2x = 300° - 30° = 270°
2x = -60° - 30° = -90°
2x = -60° - 300° = -360°
Dividing by 2 we have the complete set of solutions:
x = 15°
x = 135°
x = -45°
x = -180°
