Answer:
Step-by-step explanation:
2012 = 2500
2500 x .50 = 1250
2500 + 1250
2013 = 3750
3750 x .50 =
3750 + 1875
2014 = 5625
5625 x .50 = 2812.5
5625 + 2812.5
2015= 8437.5
8437.5 x .50 = 4218.75
8437.5 + 4218.75
2016= 12656.25
12656.25 x .50 = 6328.125
12656.25 + 6328.125
2017= 18984.375
18984.375 x .50 = 9492.1875
18984.375 + 9492.1875
2018= 28,476.5625
Answer:
cosine
Step-by-step explanation:
eliminate each ratio that will not work,
we'll just use Soh Cah Toa, which basically tells us when to use that ratio
Soh stands for sine=opposoite/hypotenuse
a sine ration would be the opposite side, but we are not given the opposite side, we are given the adjacent side, so we can eliminate this
Cah (correct answer)
Cah stands for cosine=adjacent/hypotenuse
x is the adjacent side to 27 degrees and we are given the hypotenuse, so this will work
Finally Toa won't work because
Toa stands for tangent=opposite/adjacent
We can automatically eliminate this because the tangent only uses the two legs, it does not use the hypotenuse
therefore our answer is the cosine ratio

Answer:
s = 16.97 units
Step-by-step explanation:
Since this is a right triangle, we can use trigonometry to figure out the lengths of the sides.
Look at the 45 degree angle. We can use the opposite side (12) and the hypotenuse (s) to solve for s.
Opposite and hypotenuse is sine, so we are using sine. The sine of 45 degrees is 0.70710678118. Make an equation like so:
- 0.70710678118 =
, and we are solving for s.
Put a 1 in the denominator of sine(45 degrees) so you can cross-multiply.
Cross multiply.
Divide both sides by sine(45 degrees).
The length of side s is 16.97 units.
Another way to have done this problem is to use the Pythagorean theorem: a^2 + b^2 = c^2
Substitute 12 for a and b and solve for c, the hypotenuse.
Evaluate the exponents.
Add them together.
Square root 288 to solve for c.
c = 16.97, which is the same answer as you got using trigonometry.
