Answer:
1) The angle would be 150 degrees
a) coordinates would be (
,
)
b) Trigonometric ratios:
sin: 
cos:
tan: 
csc: 2,
sec:
cot: 
Explanation:
simplifys to
which has a reference angle of
. We can take the coordinates of
and make the x value negative to find the correct coordiantes. Then, using those coordinates, plug the into the trigonomic equations.
For example, sin in opposite/hypotenuse. So sin = 1/2 divided by 1. Then you can find the rest of the equations that way.
cos= adjacent/hypotenuse
tan= sin/cos
csc= hypotenuse/opposite
sec= hypotenuse/adjacent
cot= cos/sin
Answer:
A) Between 1750 and 1760 many improvements were made. Improvements such as spinning and waving the coal on machines were examples of this.
B) Improvements such as said above helped dramatically. They helped by using their power to smelt iron and steel. Because of this, economic life improved.
C) Mining coal helped transform social and economic life. It transformed life because it pumps out deepening mines. Because of this, more and more power transfers to keep the machines running.
