In the triangle below, 4/5 represents which ratio?

ASHA 777 [7]

Answer:
sin (C)

Explanation:
In a right-angled triangle, special trig functions can be applied. These functions are as follows:
sin (theta) = $\frac{opposite}{hypotenuse}$

cos (theta) = $\frac{adjacent}{hypotenuse}$

tan (theta) = $\frac{opposite}{adjacent}$ 

Now, let's check the triangle we have:
We have two options:
First option:
5 is the hypotenuse of the triangle
4 is the side adjacent to angle B
Therefore, we can apply the cos function:
cos (B) = $\frac{4}{5}$ 

Second option:
5 is the hypotenuse of the triangle
4 is the side opposite to angle C
Therefore, we can apply the sin function:
sin (C) = $\frac{4}{5}$

Among the two options, the second one is the one found in the choices. Therefore, it will be the correct one.

Hope this helps :)

Margaux borrowed 63000 on jan. 16 2012 and paid the loan in full on may 13 2012 with 11% interest. Compute the simple interest u

sp2606 [1]

Answer:

$2234.26

Step-by-step explanation:

The formula is ...

i = Prt

Filling in the numbers, we have ...

i = $63000·0.11·(118/366) ≈ $2234.26

The year beginning Jan 16, 2012 and ending on the same date in 2013 has 366 days, so we use that for the number of days in the year. Similarly, the day Feb 29, 2012 adds one day to the interest-earning period, so there are a total of 118 days between 1/16/2012 and 5/13/2012.
