Answer:2 to 25
Step-by-step explanation:
X = 6 cos(t)
y = 3 sin(t)
we can rewrite these equations as:

Taking squares of both equations we get:

Adding both the equations, we get:
On the unit circle:
( 1, 0 ) corresponds to 0.
( 0, 1 ) corresponds to π/2
( -1, 0 ) corresponds to π
( 0, - 1 ) corresponds to 3π/2
- π = π
Answer:
D ) ( - 1 , 0 )
Answer:
Step-by-step explanation:
<u>The interior and exterior angles are supplementary:</u>
- A + 108° = 180°
- A = 180° - 108°
- A = 72°
