Tan52° = x/29
The angle of elevation is 52°, so that must be inside the tan function.
Tan is the ratio of the opposite side to the adjacent side. Jessica’s height is unknown, so we can call that x. The adjacent side of the triangle is the shadow, which is 29’m. Since tan is opposite over adjacent (remember SOH CAH TOA), the fraction must be x/29.
Answer: A
Step-by-step explanation:
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.
Step-by-step explanation:
Based off the information given, it is hard to determine the height of the elephant, therefore we are going to go through with the information given with the car.
Car: 3 + x = 5
x=2
Elephant: 15 - 2 = 13
13 ft.
2/3x-9+9=3/4+9=
2/3x=12/4
3/2)2/3x=3(3/2)
x=9/2
x=4.5
