Answer:
square inches
Step-by-step explanation:
Given



Required
The area of the triangle
To do this, we use:

So, we have:



Approximate
tangent is less than 0 or tan(θ) < 0, is another way to say tan(θ) is negative, well, that only happens on the II Quadrant and IV Quadrant, where sine and cosine are different signs, so we know θ is on the II or IV Quadrant.

Option A: 3 is the right answer
Step-by-step explanation:
Given

In an ordered pair, the x-coordinate is the input to the function and y-coordinate is the output of the function on specified input.
In the given ordered pair,
x-coordinate is -2 so we will put it into the function to get the y-coordinate
So,

3 will complete the ordered pair of the point on the graph
Hence,
Option A: 3 is the right answer
