<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:</h2>
y = 5/3x - 9
<h2>
Step-by-step explanation:</h2>
For slope intercept form, you should have the slope and the y intercept.
<em>Slope intercept form is...</em>
y = mx + b
- y being y
- m being slope
- x being x
- b being the y intercept
Moving on:
To find slope, you have to know the rise and run, or the change in y and the change in x.
<em>To find slope...</em>
(-9 - (-14)) / (0 - (-3))
Now, you should be able to calculate that to find that your slope is...
5/3 or 1 2/3
Now, you should be focused on finding your y intercept where the coordinates are (0, b) where b is your y intercept.
<em>Lucky for you, you already have your y intercept being -9 given in the question.</em>
<em />
Finally, to find the slope intercept form! You start off with your main equation for slope intercept form.
y = mx + b
Then you should plug in the numbers you have just found.
<em>Meaning your slope and y intercept...</em>
y = 5/3x - 9

Answer:
the answer is c 120 degrees
Step-by-step explanation:
Because angle 1 And angle 5 are the same angle
And it wouldn’t be 60 Because the angle would more look like a V
