Decimal Form:
![x = -267.38030...](https://tex.z-dn.net/?f=x%20%3D%20-267.38030...)
Step-by-step explanation:
![-3^{\circ \:}x\left(-3\right)=\left(-3\right)\cdot \:14](https://tex.z-dn.net/?f=-3%5E%7B%5Ccirc%20%5C%3A%7Dx%5Cleft%28-3%5Cright%29%3D%5Cleft%28-3%5Cright%29%5Ccdot%20%5C%3A14)
Remove Parentheses: ![(-a) = -a](https://tex.z-dn.net/?f=%28-a%29%20%3D%20-a)
![-3^{\circ \:}x\left(-3\right)=-3\cdot \:14](https://tex.z-dn.net/?f=-3%5E%7B%5Ccirc%20%5C%3A%7Dx%5Cleft%28-3%5Cright%29%3D-3%5Ccdot%20%5C%3A14)
Multiply the numbers: ![3 * 14 = 42](https://tex.z-dn.net/?f=3%20%2A%2014%20%20%3D%2042)
![-3^{\circ \:}x\left(-3\right)=-42](https://tex.z-dn.net/?f=-3%5E%7B%5Ccirc%20%5C%3A%7Dx%5Cleft%28-3%5Cright%29%3D-42)
Divide both sides by: ![-3^{\circ \:}\left(-3\right)](https://tex.z-dn.net/?f=-3%5E%7B%5Ccirc%20%5C%3A%7D%5Cleft%28-3%5Cright%29)
![\frac{-3^{\circ \:}x\left(-3\right)}{-3^{\circ \:}\left(-3\right)}=\frac{-42}{-3^{\circ \:}\left(-3\right)}](https://tex.z-dn.net/?f=%5Cfrac%7B-3%5E%7B%5Ccirc%20%5C%3A%7Dx%5Cleft%28-3%5Cright%29%7D%7B-3%5E%7B%5Ccirc%20%5C%3A%7D%5Cleft%28-3%5Cright%29%7D%3D%5Cfrac%7B-42%7D%7B-3%5E%7B%5Ccirc%20%5C%3A%7D%5Cleft%28-3%5Cright%29%7D)
Simplify:
![x=-\frac{840}{180^{\circ \:}}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B840%7D%7B180%5E%7B%5Ccirc%20%5C%3A%7D%7D)
Hope I helped. If so, may I get brainliest and a thanks?
Thank you, have a good day! =)
152 degrees is the same as angle 5.
Because angle 5 is 152 degrees, 180-152 = 28
Angle 7 is 28 degrees
The bottom answer is correct. I had some trouble with this so I had to find x and y in separate parts.
TO FIND X
notice that the top triangle and bottom triangles are similar, meaning if you multiple all three sides of one by a specific number, it becomes the same size as the bottom triangle.
17 x n = 8, therefore n=8/17
8 x n = X, therefore X=64/17
For some reason, this does not give a correct value for Y, so I had to use trig
TO FIND Y
Notice that the angle DAB is the same as DBC (lets call this angle Ø)
Using trig rule, we know that the cos of an angle is equal to the adjacent side divided by the hypotenuses.
We can now form some equations:
cosØ = 15/17 (from the top triangle)
cosØ = 8/Y (from bottom triangle)
Now we know that Y=(8x17)/15 = 136/15
X=64/15 Y=136/15
Answer:
1750
Step-by-step explanation:
your rule is times 5 so 350*5=1750
Answer:
12.058
Step-by-step explanation:
You steal one "count" from the 8, and move it to the 7 so you have 12.0587, instead of 12.0578. Then, you are able to take off the 7 from the back.
