Hello!
First of all, let's find A. This is the opposite and hypotenuse we will be dealing with. Therefore, we will use the sin.
sin30= 0.5
This gives us the equation below.
a/12=0.5
a=6
Now we find b. This is the adjacent and hypotenuse. Therefore, we will use the cosine.
cos30≈0.87
This gives us the equation below.
b/12=0.87
b=10.44
I hope this helps!

Answer:
The total number of pencils that Mr. Moretti gives to his is 162.
Step-by-step explanation:
He puts 3 mechanincal pencils in each bag.
In each bag, there is also twice as many regular pencils, that is, 3*2 = 6 regular pencils.
So in each bag, 3 + 6 = 9 pencils.
What is the total number of pencils that Mr. Moretti gives to his students if he puts 3 mechanical pencils in each bag?
18 students, and each gets 9 pencils.
18*9 = 162
The total number of pencils that Mr. Moretti gives to his is 162.
Answer:
Bow ties: 1/5
Cheese sauce: 1/4
Bow ties with cheese sauce: 1/20
Step-by-step explanation:
There are 3 different questions here.
First, you have the pasta question. What is the probability you'll end up with bow ties? Well, there are 5 kinds of pasta, all with the same chance to be chosen... so you have 1 chance out of 5 to pick bow ties.
Then the sauce. Same logic... 4 different sauces... so 1/4 chance to get the cheese sauce.
For the bow ties and cheese sauce combo, it's a bit different, we're talking about compound probabilities here.
So, you have to multiply the probability to get bow ties with the probability to get cheese sauce, so:
Answer:
1057.89 feet
Step-by-step explanation:
Trig time! Start with a diagram and listing out your trig functions, either mentally or on paper. SOH CAH TOA
The best trig function for this problem is likely tan:
tan84.6 = height / 100
100 * tan 84.6 = height
height = 1057.89 feet
