We know that
applying the law of sines
50/sin 40=60/sin x
50*sin x=60*sin 40
sin x=[60*sin 40]/50
sin x=0.7713
x=arc sin (0.7713)----> x=50.47°--------> x=50.5°
the answer is
x=50.5 °

Answer: It's good to think about things before doing them because it is more thought out and you have a better chance of getting things correct whereas without thinking your most likely going to get it wrong. Without thinking through your options you are basically guessing the answer. I hope this helped you have a great day and god bless you :D
5 units over
with a scale factor of .5
What this is asking is how do you turn the one shape into the other. The first answer is how many spaces apart they are. In this case the smaller rectangle EHGF was 5 units (or squares over... Also note that the fact that the larger rectangle is higher doesn't matter because the space is reduced when it is shrunk). The second answer was talking about how much smaller it was. This is identified by counting the sides. rectangle EHGF had sides 1 unit (square) and 2.5 units (squares) long this is half or .5 of the larger ABCD's 2 units (squares) and 5 units (squares).
