The triangle is a right triangle with:
1) leg c opposed to angle C.
2) leg b opposed to angle B.
3) hypotenuse, a, opposed to angle A.
So, using the definitions of the trigonometric ratios, you get:
1) sin C = opposite leg / hipotenuse = c / a.
2) tan B = opposite leg / adjacent leg = b / c
=> sin C * tan B = [c / a] * [b / c] = b / a.
<span>Answer: b / a</span>
Ratio of shadow to object's size = 2/7
Then, size of tree would be: 7/2 * 28 = 7 * 14 = 98 feet
So, your final answer is 98 feet

This is called the Associative Property of Addition.
In short, associative property of addition states that the quantity of an additive expression is going to be the same no matter how the expression is grouped. In this case, it doesn't matter whether 6+3 is added first or 3+21 is added first because they will end up with the same quantity.
Answer: The conclusion is valid
Step-by-step explanation:
Number of students surveyed = 50
Number of students who visited a science museum = 20
Number of students who haven't visited a science museum = 30
Percentage of student that have visited a Science museum:
= 20/50 × 100
= 40%
The conclusion is valid based on the calculation.
