Answer:

Step-by-step explanation:
10 * sqrt(81/25 * -1) = 10 sqrt(81/25) * sqrt(-1) = 10 *9/5 * i
20: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200
14: 14, 28, 42, 56, 70, 84, 98, 112, 126, 140
140 is the smallest number they have in common.
Answer:
or 8:17
Step-by-step explanation:
For any angle x (other than right angle) in a right triangle ,the trigonometric ratio of sin x is given by :-

Given: A right triangle with hypotenuse = 68 units
The side adjacent to S = 60
Let h be the side opposite to S, then using Pythagoras in the given right triangle, we get
Thus, the side opposite to S = 32 units
Now, the trigonometric ratio for sin S is given by :-

Hence, the trigonometric ratio for sin S =
or 8:17
Answer:
Step-by-step explanation:
1-4
1
n=30/1
so it would be (t,n) instead of (x,y) respectively
so the first would be (1,30)
2. n=30/2
second would be (2,15)
3. n=30/3
third would be (3,10)
4.
n=30/4
fourth would be (4,7.5)
