Answer:
θ = π n - 20 for n element Z
Step-by-step explanation:
Solve for θ:
sin(θ + 20) = 0
Take the inverse sine of both sides:
θ + 20 = π n for n element Z
Subtract 20 from both sides:
Answer: θ = π n - 20 for n element Z
Answer:

Step-by-step explanation:
First, we open the parentheses by multiplying the contents of the parentheses by 3 (because it says 3(2x+6)). The final result is <u>6x+18</u>
Check the picture below.
so, if we add all the arcs provided, we have a total of 153° + 60° + 53°, which gives us 270°.
keeping in mind that a circle has a total of 360°, the shaded region has to be a sum of 360° - 270°, or 90°.
now, notice the tickmarks on those angles in the graph above, meaning those two angles are twins, and 90°/2 is 45°, so each of those twins is 45°.
arcYW = 60° + 45°.
