A= 3,3
B= -2,3
C=-1,-1
D=1,-3
The answer is going to be 15
<u>Given</u>:
The given triangle ABC is a right angled triangle.
The length of AC is 4 units.
The measure of ∠B is 20°
We need to determine the length of BC.
<u>Length of BC:</u>
The length of BC can be determined using the trigonometric ratio.
Thus, we have;

From the figure, the side opposite to the angle is AC and adjacent is BC.
Substituting opp = AC and adj = BC, we get;

Substituting AC = 4, we have;

Simplifying, we have;



Thus, the length of BC is 10.99 units.
Answer:
The original cost is $59.82
Step-by-step explanation:
x(1.3)=77.77
x=59.82
Answer:
its option 1
Step-by-step explanation:
D, because if u plug it in both the equations, you will get the same solution.
y=x-1
2=3-1
2=2
y=-3x+11
2=-3(3)+11
2=-9+11
2=2
