Answer:
133.5
Step-by-step explanation:
Area of paralleogram is base x height. The base is 15 as given. We need to find the height.
Using triangle MNJ we can find it.
We need to find side MN but we are given an angle adjacent to that side 90. We also given another angle and a side adjacent to that angle 52 and 7 respectively.
We can use law of sines to find MN
sin of 90 =1 so multiply 1 by both sides
simplify that and we get mn=8.9.
So know we can multiply 8.9 by 1t to find the area.
15×8.9=
133.5
Let's write 2 equations from the two statements given.
<em>Sarah spent 10 dollars on both oranges and apples</em>
<em />
Let the price of oranges be "x" and price of apples be "y", thus we can write:
Oranges cost 3 less than apples, thus we can say:
We can substitute this into the first equation and solve for y:
Thus, let's solve for x now,
We want the price of oranges (x), thus,
<em>Price of Oranges = $3.50</em>
