so hmmm which is it, the +/-? well, we know that <span>tan(θ) < 0, that means the tangent of the angle is negative, well, the tangent is opposite/adjacent, the only way that fraction can be negative, is that if either, no both, just either opposite or adjacent is negative.
well, we know the opposite is +1, so, the adjacent then has to be negative, so is -2√(2) then
</span>
The answer is A, B, and C
Answer:
x = 180 - 89 = 91
Step-by-step explanation:
Answer:
46degrees
Step-by-step explanation:
The sum of angles of exterior angles of a quadrilateral is 360 degrees
Hence;
72 + 58+2x+3x = 360
130 + 5x = 360
5x = 360-130
5x = 230
x =230/5
x = 46 degrees
Hence the vale of x is 46degrees
Hi there!
You might already know the first step:
We can find the profit of a company by subtracting the total cost from the total revenue.
Profit = revenue - cost
We can now plug in (substitute) the functions from the question and find the profit function.
Profit = (20X) - (180 + 8X)
Work out the parenthesis. Pay attention to the minus sign in front!
Profit = 20X - 180 - 8X
Collect the terms.
Profit = 12X - 180
P = 12X - 180.
When a company sells breakeven, their total revenue equals their total cost and therefore they have no profit. This leads us to the conclusion that P = 0. Let's solve the equation!
12X - 180 = 0
Add 180 to both sides.
12X = 180
Finally divide by 12.
X = 180 / 12 = 15
Hence, the company must sell 15 bracelets to sell breakeven.
~ Hope this helps you!
