<span><span>The
tangent of an angle is the ratio of the opposite leg length to the adjacent leg
length.
The correct answer would be c, tangent.
To summarize, a tangent is </span><span>a straight line or plane that touches a curve
or curved surface at a point, but if extended does not cross it at that point.</span></span>
Okay, it's the equation to how find area any other way. A=L×W
This means *picture above*
So then you count over each line meaning 1.
This means L=9 and a 1/2. Since its in between the 2 an 3 on the x-axis.
Now for W or width. It equals 3 since you can count 2 lines and one either ends of the polygon is 1/2 each this creates one when added together.
All you do from there is multiply 9 and 3. This should give you A=area.
