Answer:

Step-by-step explanation:
Recall that in a right triangle, sine is the ratio of the opposite side to the hypotenuse:

We are actually not given the opposite side in this case. However, since we know the hypotenuse and the adjacent side, we can use the Pythagorean Theorem to find the opposite side. So:

Let <em>a</em> be the adjacent side and <em>b</em> be the opposite side. <em>c</em> will be the hypotenuse.
Substitute:

Solve for <em>b: </em>

<em />
So, the opposite side measures 12.
Then sine will be:

Answer:
18.5
Step-by-step explanation:
First find the area of the two triangles.
1.5 * 1.5 = 2.25
Find the area of the two top rectangles: 2.5 * 1.7 * 2 = 8.5
Finally, find the area of the floor: 1.5 * 2.5 = 3.75
2.25 + 8.5 + 7.75 = 18.5

Step-by-step explanation:

Answer:
20.7 --> 21
9.18 --> 9
21x9 is 189, thus the estimated product is 189.

Answer:
a.) 1/2
b.) 1/8
c.) 5/8
d.) 1/2
Step-by-step explanation:
for A it is asking for probability of 1 and is 1/2 of the circle
for B it is asking for probability of 3 and it is 1/2 of and 1/4 of the circle so 1/8
for C it is asking for probability of the odd numbers and there is tow odd numbers 1 and 3 the probability of 1 is 1/2 and the probability of 3 is 1/8 adding them up will give you 5/8
for d it asks for the probability of at least 2 so therefor 2, 3, and 4 and they are 1/8 + 1/8 + for 1/4 = 1/2
