Answer:
a. 53
Step-by-step explanation:
The side with length 15 is opposite the right angle, so it is the hypotenuse of the right triangle.
For angle x, the side measuring 12 is the opposite leg.
Our 3 items of interest are: angle, opposite leg, hypotenuse.
The trig ratio that relates the opposite leg to the hypotenuse is the sine ratio.
sin x = opp/hyp
sin x = 12/15
sin x = 0.8
Now we take the inverse sine of 0.8 to find the measure of the angle.
x = sin^(-1) 0.8 = 53 deg
612
x 87
----------
4 284
4 896
----------
53 244
612*87 = 53244
For 2/5 meter, it takes = 1 min.
For 1 meter, it is = 5/2 min.
Now, for 6 meters, it would be: 5/2 * 6 = 30/2 = 15
In short, Your Answer would be 15 minutes

Using the unit circle, the coordinates of the terminal point corresponding to 
is: (-0.5, 0.866).
<h3>What is the unit circle?</h3>
For an angle 
the unit circle is a circle with radius 1 containing the following set of points: 
.
In this problem, the angle is of , hence:
.
.
Hence the terminal point is:
(-0.5, 0.866).

Answer:
12 sweets
Step-by-step explanation:
2:5:3.
caroline gets 12 so multiply the ratio by 6.
12:30:18
Krutika has 30, Natasha has 18.
30-18=12
so 12 sweets
