Answer:
1/2
Step-by-step explanation:
Step 1: You would multiply 2/3 by 3/4.
(Hint: if it is ____ of ____, you would most likely multiply)
Step 2: 2×3/3×4
Step 3: 2×3=6
Step 4: 3×4=12
Step 5: 6/12
Step 6: Simplify 6/12 = 3/6 = 1/2
Hope this helps :)
4) The line segments formed are parallel because they never meet.
8) The answer is B. That is because there is a right angle and right angles are formed by perpendicular lines.

Your question is incomplete.
If you want me to tell the ratio, its 3:2
Sin angle that equals the 1/2 value is the 30 degree on the 1st Quadrant.
The angle of 30 degree on the 3rd Quadrant is equivalent to (formula and circle in the 1st photo) 180 + 30 = 210°.
So theta = 210° (3rd Quadrant) = 30° (1st Quadrant).

Now just transfer the cos 30° to the 3rd Quadrant and the signal will be negative (as shown in the 2nd photo attached).
