Answer: H
Step-by-step explanation:
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:
see below.
Step-by-step explanation:
The two lines are parallel with different y intercepts. That means they never intersect. The solution to the system of equations is where they intersect. This means there is no solution to the system of equations.
Answer:
a = -3
Step-by-step explanation:
−40 + 10a = -70
10a = -70 + 40
10a = -30
a = -30/10
a = -3
