The major trigonometric ratios at this level include sine, cosine and tangent.
sine is the ratio of opposite to hypotenuse, cosine is the ratio of adjacent to hypotenuse while tan is the ratio of opposite to adjacent. Therefore, in this case our adjacent is 15, To get the hypotenuse we use the pythagoras theorem
15² + 9² = 346, thus the hypotenuse will be √346.
Hence, cos B will be 15/√346
This is a conversion problem..

Answer:
the amount paid in total is $1,100
Step-by-step explanation:
The computation of the amount paid in total is shown below:
= Total persons × cost of each one ticket
= (12 boys + 18 girls + 14 boys) × $25
= 44 persons × $25
= $1,100
Hence, the amount paid in total is $1,100
Check the digit on the hundreds place.
- If the digit is between 0 to 4, round down.
- If the digit is between 5 to 9, round up.
For example:
1) 4567
The digit in the hundreds place is 5, so we will round up.
4567 = 5000 (nearest thousand)
2) 4467
The digit in the hundreds place is 4, so we will round down.
4567 = 4000 (nearest thousand)
The answer is -5 because 4 times -2 is -8 and (-8) - (-3) is -5
