Answer:
Step-by-step explanation:
Given
Required
Determine the
<em>- sin</em>
<em>- cosine</em>
<em>- tangent</em>
of an angle
The given expression can be represented as follows;
Where A = 94 and B = 37
In trigonometry:
Substitute 94 for A and 37 for B
Hence, the angle is 57;
<em>Since 57 is not a special angle; I'll solve using a calculator</em>

Step-by-step explanation:
When in doubt, it can help to plot the points on a graph.

By looking at the coordinate values, you see that the first two points have the same y-coordinate (0) and the other two points have the same y-coordinate (-4). These points are on horizontal lines that are 4 units apart.
Looking at the x-coordinates, you see that one pair of points has x-coordinates 4, and the other pair has x-coordinates 8. That is, these pairs of points are on vertical lines that are 4 units apart.
Vertical and horizontal lines are at right angles to each other. That means the figure must be a rectangle or square. The lengths of the sides are all 4 units, so the figure is a square.
