Answer:
x = 60
Step-by-step explanation:
The 60° angle and angle x both have 2 marks, so they are congruent.
x = 60
Answer:
D
Step-by-step explanation:
Multiply both sides by 12 to get x+36<_84.
Then move the constant to the right to get x by itself: x<_84-36
Subtract 36 from 84 to get 48.
Now you're left with x<_48
btw <_ is less than or greater than i just don't know how to place the sign on top of the underscore :/ hope this helped :)
Quick answer Sin(570) = - 1/2
Comment
570 as an angle contains 1 complete revolution of the terminal arm. The terminal arm begins at the origin and the other (in this case swings around until it records 570° turning around the x axis in an anticlockwise direction.
Anticlockwise means going from 12 o'clock to 9 o'clock to 6 o'clock then 3 o'clock and back to 12 o'clock.
What is 570° (∅) degrees equivalent to?
We keep on subtracting 360 until we get a number between 0 and 360 inclusive.
Written this way 0 ≤∅≤360
570 - 360 = 210°
So we need to find the equivalent of 210°
Method
210° = 180° + 30°
This means that ∅ is 30° below the x axis in the 3rd quadrant.
Sin(30) = 1/2
In the third quadrant, the sine is minus. so
sin(210°) = - 1/2 <<<<<<< Answer
