Answer:
$2.61
Step-by-step explanation:
I think you mean 0.95 dollars per pound. 0.95 cents means it's less than a dime per pound.
We are given the hypotenuse, an angle, and a side that is <em>adjacent </em>to the angle. If we need to find the angle, we use a trigonometric ratio known as cos(x):
We need to solve for x, so we need to cancel cos from the other side. The inverse of cos(x) is arccos(x):
Now, we can safely solve for x:
So, your answer is:
x = 58.85°.
For this case you can solve the problem by applying a simple rule of three in which we have
520 ---> 100%
800 ---> x
Clearing x we have
x = (800/520) * 100 = 154%
the percentage increase in cost was
154-100 = 54%
answer
the percentage increase in cost was 54%
Answer:
x = 5
Explanation:
Well, there's a theorem about these triangles that helps you solve questions similar to this one.
The theorem states that the sum of the two angles of a triangle is equal to the magnitude of the angle exterior to them.
That is, 33° + (10x+1)° = (17x-1)°
17x - 10x = 33 + 1 + 1
7x = 35 => x = 5
Hope it helps you, mate! :)
