Answer:
See image
Step-by-step explanation:
It helps a lot to draw a triangle. Sin is OPPOSITE/ HYPOTENUSE. You can use Pythagorean thm to find the third side. Then use cos = ADJ/HYP
tan = OPP/HYP
Then, find reciprocal functions. Reciprocal just means you are flipping the ratios over.
csc = HYP/OPP
sec = HYP/ADJ
tan = ADJ/OPP
The only tricky remaining part is that you cant leave a radical (the square root symbol) on the bottom of a ratio. So you have to fix those. See image.
I think it's 4 if I'm wrong I'm sorry
In order to know how much time will David and
Armando take, you need to write down the given and solve them with the given
solution.
David – 15 reports
Armando – 37 reports
Total Reports = 52 reports in total
Total Reports in an hour = 52
Overall total reports = 400
Time to finish = ?
If you try to evaluate, if you have 50 reports in
an hour with a total of 400 reports, you could have gain 8 hours by doing the
reports.
So to expand more, 52 reports will be divided
into 400, giving a total of 7.6
<span>So the answer is that they will take 7 hours
and a half in doing the reports.</span>
Answer:
(in order) #1
for the first one you have a vertical angle. Vertical angle is basically any 2 lines who intersect each other. The opposite sides will be congruent.
So in this case
2x+8 and 110 are oppostie sides.
2x+8=110
Which is x= 51
#2
For the second one you have supplementray angles
Now for supplementary angles its basically 2 angles added up that form a straight line And 180 degress is always the measure of a straight line. SO in this case we do
9x+12x+75=180
Which is x=5
#3
This is also a vertical angle pair and their congruent just like #1
So 5x+5=65
x=12
