Answer:
cos Ф = adj / hyp could be either 4/5 or -4/5.
Step-by-step explanation:
If sin Ф = 3/5, then we can assume that the opposite side is 3 and the hypotenuse is 5. Using the Pythagorean Theorem, we find that the adjacent side is 4:
√(5² - 3²) = √16 = ±4.
cos Ф = adj / hyp could be either 4/5 or -4/5.

Step-by-step explanation:
because if it were to go up 750 every minute then it would have to be proportional. :)
Answer:
10%
Step-by-step explanation:
First, get the drop in value by deducting the price this year from last year's price.
Value decrease=$52.00-$46.80=$5.20
To express it as a percentage, we divide it by the original price which was $52.00 then multiply by 100 hence the percentage decrease will be

Therefore, the price decreases by 10%
The answer should be AC+BC
We can answer this by applying the rule called "Greater angle, greater side". This is where in any triangle, the opposite side of the larger angle is also longer.
So in this question, first we have to find the largest 2 angles, which is ∠ABC and ∠BAC with measures of 120° and 35° respectively. Therefore, from the diagram, the opposite sides of the angles are AC and BC.
Therefore, the answer should be AC+BC.
