Answer:
cos(C)
Step-by-step explanation:
Recall that the sine ratio is opposite over hypotenuse.
Also the cosine ratio is adjacent over hypotenuse.
The tangent ratio does not come close because it doesn't involve the Hypotenuse.
In order to know what is the reasonable amount of tile for
Mandana to order, you have to divide the choices with the area of the floor and
deduct with 1 and multiply by 100. You have to assess if the answer you will
get will fall between 15% and 20% which is the goal of Mandana.
<span>a.
</span>131/116.9 = (1.1206 – 1) x 100 = 12.06%, this
does not fall between 15% and 20%
<span>b.
</span>138/116.9 = (1.1805 – 1) x 100 = 18.05%, this
fall between 15% and 20%
<span>c.
</span>133/116.9 = (1.1377 – 1) x 100 = 13.77%, this
does not fall between 15% and 20%
<span>d.
</span>141/116.9 = (1.2062 – 1) x 100 = 20.62%, this
does not fall between 15% and 20%
Therefore, the reasonable amount of tile for Madana to order
that is between 15% and 20% extra of the materials is 138 square feet.
I think its 2 because if you divide 20,000 over 1000 you get 2. If you do that for the other values, you would also get 2.
7,458 is the answer because 12% of 8475 is 1017 8475-1017 = 7458 so being the answer.
D) a reflection in the line y = x
