Answer:
The size of the angle formed at the top of the sail is 35.
Step-by-step explanation:
We know that the sum of all angles inside a triangle must be 180. This is a rule.
So we know that a right triangle is called like that because one angle is a 90-degree angle.
Then we have that:
180 = right angle + lower edge angle + angle top of the sail
180 = 90 + 55 + angle top of the sail
Solving for 'angle top of the sail' we have:
angle top of the sail = 180 - 90 - 55 = 35
The size of the angle formed at the top of the sail is 35.
Answer:
(Opt.B) 18
Step-by-step explanation:
4x = 2y - x (vertically opposite angles are equal)
4x + x = 2y
5x = 2y ----- (1)
4x + 2y + x = 180 (Linear pair angles)
5x + 2y = 180
From (1) we can understand that, the value of 5x and 2y is the same. So,
5x + 5x = 180
10x = 180
x = 180/10
x = 18
Just completing,
Putting the value of x in (1)
5*18 = 2y
90 = 2y
90/2 = y
45 = y

The formula in getting the ROI or the Return on Investment is ROI = Net Profit/ Total Investment x 100. Below is the solution:
ROI = $ 75,000/$1500 x 100
ROI = $ 5 x 100
ROI = $ 500
You will then divide the $ 500 by 6 to get the ROI per year which is equals to $83.33
Answer:
A proportional relationship is states that they are the same. For example, 1/2 and 6/12 have a proportional relationship, which means they are the same.
