Do cross multiplication
<u>6</u> = <u>x</u>
18 12
Now cross multiply
(6)(12) = (18)(x)
72 = 18x
Divide both sides by 18
<u>72</u> = <u>18x</u>
18 18
4 = x

Answer:
B. 50 degrees
Step-by-step explanation:
I am not 100% sure and if this is a right triangle, then it's measure is 90 degrees. So, 140 degrees minus 90 degrees would total, 50 degrees.
Answer:
-2.26 lb
Step-by-step explanation:
Let the dog's initial weight be d.
Then, one year later, the dog weighs 3.73 lb less, and thus weighed d - 3.73 lb.
During the next year, the dog gained 1.47 lb, so now weighs d - 3.73 + 1.47 lb, or
d - 2.26 lb. This indicates a total weight loss of 2.26 over these two years.
Given:
![\sin \theta](https://tex.z-dn.net/?f=%5Csin%20%5Ctheta%20%3C0)
![\tan \theta](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%20%3C0)
To find:
The quadrant in which
lie.
Solution:
Quadrant concept:
In Quadrant I, all trigonometric ratios are positive.
In Quadrant II, only
and
are positive.
In Quadrant III, only
and
are positive.
In Quadrant IV, only
and
are positive.
We have,
![\sin \theta](https://tex.z-dn.net/?f=%5Csin%20%5Ctheta%20%3C0)
![\tan \theta](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%20%3C0)
Here,
is negative and
is also negative. It is possible, if
lies in the Quadrant IV.
Therefore, the correct option is D.
