Answer:
Step-by-step explanation:
Firstly, let find some some other trig functions. We need to know all sides to know other trig functions. We know the horizontal side is -7 because it x-axis is at -7, it y-axis is at 24. so it vertical side is 24. Then we use the pythagorean theorem to find r
49+576=
525=c^2
So since we know that x= -7, y=24, r= 5 times sqr root of 21. We can find some trig functions. We can use function cosine here. Cosine equals
cos=
then we find secant which is the reciprocal of cos so we flip the numbers and that equals
Answer:
- 210 degrees
- -150 degrees
Step-by-step explanation:
When the time is 3:40pm
- The Initial Side (hour hand) is at 3.
- Terminal Side (Minute hand) is at 8.
(a)The angle between the two hands in standard position is drawn and attached below.
(b)Now, each hour = 30 degrees
Therefore, the angle between 3 and 8 in an anticlockwise movement
= 7 X 30 =210 degrees
Stating the angle as a negative angle, we have:
