Answer:
D
Step-by-step explanation:
CD is an angle bisector and divides the opposite side into segments which are proportional to the other 2 sides, that is
=
, substitute values
=
( cross- multiply )
3x = 9 ( divide both sides by 3 )
x = 3 → D
Answer:
I'm sorry I really need points to ask a question for a really big math test! :(( pls no report this is a huge test
Step-by-step explanation:
The formula for a cube is l x w x h. But, these are all the same. So, you multiply 4 by 4 three times. The volume of the cube is 64^2 inches.
a pair is 2 so
132 divided by 2 is 66
so 330 divided by 66
is five then you add the original dogs
The answer is 7 dogs
Answer:
<em>1st triangle:</em>
sin(C): 0.64, ![\frac{16}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B25%7D)
cos(C): 0.8, ![\frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D)
<em>Second triangle:</em>
sin(C): 0.75, ![\frac{\sqrt{5} }{3}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B5%7D%20%7D%7B3%7D)
cos(C): 0.67, ![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
Step-by-step explanation:
Using SOH CAH TOA, we know that to find the sin of an angle, it's Opposite/Hypotenuse.
To find the cos of an angle, it's adjacent/hypotenuse.
<u>In the 1st triangle:</u>
The adjacent to C is 16, the hypotenuse is 25.
is the sin of C.
The adjacent to C is 20, and the hypotenuse is 25.
is the cos of C.
<u>In the second triangle:</u>
The opposite to C is
and the hypotenuse is 2.
is the sin of C.
The adjacent to C is 2 and the hypotenuse is 3.
is the cos of C.
Hope this helped!
