20/2= 10

John makes 10 dollars an hour.


50/4= 12.5

Sally makes 12.50 dollars an hour.

Sally makes more than John. 

I hope this helps!

John gets $10 per hour and Sally makes $12.50 per hour so Sally makes $2.50 more then John per hour.

We can tell John makes $10 per hour because we divid how much he made by the amount of hours it took to make to get 10 and we did the same thing for Sally ($50/4=12.5) and then we subtract Sally's pay per hour by John's pay per hour to see how much more Sally makes per hour. 

I hope that helped and made sense. :)

Use the laws of Sines and law of cosines to find missing dimensions​
Andrei [34K]

Answer:

A) ERROR

B) ∠C = 26°

Step-by-step explanation:

Houston, We have a problem!!! too much information

If we had a legit triangle, the law of sines would hold

19/sin138 = 8/sin20

  28.395 = 23.390

as this is NOT an equality, the triangle does not exist as described.

IF it did, we'd get different results depending on which set we used

∠F = 180 - 138 - 20 = 22°

Law of sines

19/sin138 = DE/sin22 ⇒ DE = 19sin22/sin138 = <u>10.63697...</u>

or

8/sin20 =  DE/sin22 ⇒ DE = 8sin22/sin20 = <u>8.762211...</u>

If we attempt to use Law of cosines

DE² = 19² + 8² - 2(19)(8)cos22 = <u>11.9639...</u>

so really none is correct because we attempt to use trig calculations to a non-triangle.

12) AC² = 15² + 19² - 2(15)(19)cos120

      AC = 29.51270...

29.51270 / sin120 = 15/sinC

C = arcsin(15sin120/29.51270) = 26.1142... <u>26°</u>
