Which of the following equations models the relationship of angle A to the length of the line segment BC in the figure below.
Anastasy [175]
Let the line segment BD be x, then sin A = x/15
or, x = 15sinA
Also y^{2} =  x^{2} + (25)^{2}  \\ =  (15sinA)^{2} + 625 \\ =225 sin^{2} A+625 \\ y= \sqrt{225 sin^{2} A+625} &#10;

Please help and explain very easy good luck
Mars2501 [29]

Answer:

-76

Step-by-step explanation:

A positive digit multiplied by a negative digit will result as a negative digit.

So,

6 · -8 = -48

Now if there is a problem where a number is added by a negative digit number, you turn the "plus" sign into a "negative" sign.

So,

- 48 + (- 28)

-48 - 28

If you subtract a negative by a negative, the answer will be negative BUT you have to ADD those two negative digits together and put the negative sign after.

- 48 - 28 = -76
