We can model the problem using a right angle triangle.
The two sides, AB and BC are equal
By Pythagoras, we find the length of AC =
=
Using the sin ratio ⇒ sin θ = opposite/hypotenuse, we have
Using the cos ratio ⇒ cos θ = adjective/hypotenuse, we have
Using the tan ratio ⇒ tan θ = opposite/adjective, we have
Answer:
y = 2x
Step-by-step explanation:
Parallel line share the same slope, therefore we can put any parallel line of y = 2 (x + 1) in equation as: y = 2x + k
As the parallel has to intercept with point (2/3, 1/3), simply put the coordinate into the equation to get value of k
2/3 = 2(1/3) + k
k = 0
Therefore the equation of this parallel line is y = 2x
I believe that the answer is B. 62°
Answer:
(b)The original price of the shoes is $60.
Explanation:
Part A
In this situation:
• 15% is the PERCENT
,
• $9 is the PART
,
• The original price is the WHOLE.
Part B
If 15% is taken off, the customer will save $9.
This means that 15% of the original price = $9.
Let the original price=p
The original price of the shoes is $60.
