Answer:
Step-by-step explanation:
12.4
you have to multiply 1 5/9 times 8
N=-6
-6 minus 6 is -12
-12 /3 is -4 since the negative doesn’t cancel out
Answer:
A
Step-by-step explanation:
First, we need to find the unknown angle of the triangle.
40 + 20 = 60
180 - 60 = 120
So the unknown angle is 120.
Then, we can use the law of sines to create a proportion.
sin(120)/8 = sin(40)/a
Then, we can simplify this.
a is about 5.9, or answer choice A.
