Solution: We know that:
Paul and Brett went to math class and were given the same expression to simplify. The expression they were given was 6 + 12 divided by 2(3) + 1.
Looking at the solution's by Paul and Brett, we clearly see that the Paul made a mistake at step 3.
6 + 12 ÷ 2(3) + 1
6 + 12 ÷ 6 + 1 Correct
18 ÷ 6 + 1 Incorrect It should have been 6 + 2 +1
According to order of operation's rule, division needs to done before addition.
Therefore, solution by Paul carries a mistake, while the solution by Brett is correct.
In word problems on topics of trigonometry, the terms of angle of depression and angle of elevation are very common. The angle of depression is used when the observer is above the point of reference. The angle made from the observer to the object is the angle of depression. To understand more clearly, refer to the attached picture.
Suppose the dog is on the top vertex of the triangle while the cat is the rightmost corner of the triangle. The angle denoted as x° is the angle of depression. To determine this, we use the tangent function. The tangent of an angle is the ratio of its opposite side to its adjacent side.
tanx° = 16/4.5
x = 74.29°
