Hello!
When doing Sine, Cosine and Tangent the sides of the triangle tell you what to do
The hypotenuse is H
The bottom side is A
The Straight up and down side is O
For Sine you do O / H
For Cosine you do A / H
For Tangent you do O/ A
Put in the values you Sine
Sin A = 5/ 13
Put in the values for Cosine
Cos A = 12/ 13
The answer is A) Sin A = 5/ 13, cos A = 12/ 13
Hope this helps!
Answer:
2 because id you take 3 times 2 its 6 divided by 3 is 2
Answer:
I think this is correct. I use demos calculator in 8th grade
Answer:
2.7 miles
Step-by-step explanation:
You have to be very careful how you set this up. For every girl (who counts as 1) there are 3 boys (who count as 3). The total number in the proportion is 3 + 1 =4. You are given a total, but that is both boys and girls. That's why you need the 4.
3/4 = x / 236 Cross multiply
4x = 3 * 236
4x = 708 Divide by 4
x = 708/4
x = 177
There are 177 boys at the school and 236 - 177 = 59 girls.
