Ksju [112]

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

$\frac{mn}{ \sin(90) } = \frac{7}{ \sin(52) }$

sin of 90 =1 so multiply 1 by both sides

$mn = \frac{7}{ \sin(52) } \times 1$

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

Mark bought refreshments. Sandwiches were 2.50 each and bottles of water were $1.25 each. He spent $356.25 on a total of 180 ite

Over [174]

First you have to write the equation. in the scenario, use standard form.
Ax+By=C
plug the numbers in. A=2.50, B=1.25, and C is the total, 356.25. the 180 doesn't come in quite yet.
your equation is 2.50x+1.25y=356.25. now, since they only bought 180 items, you can't go past that.

I am sorry, but I am about to leave for school, and therefore do not have enough time to answer the last of your question. I hope the part I could answer has helped you.
