Mathematics
1 answer:
Nikolay [14]2 years ago
3 0

Step-by-step explanation:

Remember to follow the rule: SohCahToa:

Sin (S) = Opposite/Hypotenuse

Cos (C) = Adjacent/Hypotenuse

Tan (T) = Opposite/Adjacent.

Hypotenuse is always the longest side. Adjacent is the side next to the angle, Opposite is the side opposite of the angle.

Sin(A) = (Opposite/Hypotenuse) = 8/17

Tan(A) = (Opposite/Adjacent) = 8/15

Cos(A) = (Adjacent/Hypotenuse) = 15/17

Sin(B) = (Opposite/Hypotenuse) = 15/17

Tan (B) = (Opposite/Adjacent) = 15/8

Cos (B) = (Adjacent/Hypotenuse) = 8/17

A film lasts 2 hours and 35 minutes. Greg is going out at 8.15 . If he starts watching the film at 5.30 will he have time to war
Dmitry [639]

Answer:

Yes, he will have enough time to watch the entire film.

Step-by-step explanation:

5:30 to 6:30 is 1 hour of the movie completed.

6:30 to 7:30 is 2 hours completed.

7:30 plus 30 minutes brings him to 8:00.

8:00 plus the additional 5 minutes brings Greg to 8:05.

His movie ends at 8:05, so he will be able to watch the entire movie before going out.
