Answer:
G. (8,6)
Step-by-step explanation:
remember that EF is four times the length of DE
so the distance between E and D multiplied by 4 should equal F
Answer:
2. tan 280°
3. -tan 80°
Step-by-step explanation:
Your calculator can help you figure this out.

The tangent function is periodic with a period of 180°, so tan(100°) will be equal to tan(100°+k·180°) for any integer k. Answer choices include k values of ±1, so two of them are correct:
- tan(100°) = tan(100° -180°) = tan(-80°)
- tan(100°) = tan(100° +180°) = tan(280°)
