Twice(2*) the measure of an angle(x)'s compliment(180°-x) less than 6(-6) is equal to 124°.
![2*(180-x)-6=124\\\\2*(180-x)-6+6=124+6\\\\\frac{2*(180-x)}{2}=\frac{130}{2}\\\\180-x=65\\\\180-x+x=65+x\\\\180-65=65+x-65\\\\\\x=115](https://tex.z-dn.net/?f=2%2A%28180-x%29-6%3D124%5C%5C%5C%5C2%2A%28180-x%29-6%2B6%3D124%2B6%5C%5C%5C%5C%5Cfrac%7B2%2A%28180-x%29%7D%7B2%7D%3D%5Cfrac%7B130%7D%7B2%7D%5C%5C%5C%5C180-x%3D65%5C%5C%5C%5C180-x%2Bx%3D65%2Bx%5C%5C%5C%5C180-65%3D65%2Bx-65%5C%5C%5C%5C%5C%5Cx%3D115)
Thus your answer is 115°
Answer:
Your friends data
Step-by-step explanation:
The rule of statistics is: the more exact the data, the better.
Here it seems that you got less precise data, as you can see. This also causes the possibility of mistakes.
This is because when you have data that is more exact, you get a better estimation for mean, median, etc. This can help make patterns in your data.
This means that your friend had better data than you.
Hope this helped!
Answer:

−8x−9
Step-by-step explanation:
You have to factor the expression in order to get your answer
Do this by expanding out the expression: (x-10)(x-10)
Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.
Multiply x and x to get , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together: . Then combine like terms
Step-by-step explanation:
LHS= sin 3x/sin x - cos 3x/cosx
Taking LCM,
<u>=</u><u>sin3xcosx- cos3xsinx</u>
sinxcosx
<u>=</u><u>sin(3x-x)</u>
sinxcosx
= <u>2sin2x</u>
2sinxcosx
=<u> </u><u>2sin2x</u><u> </u>
sin2x
=2
= RHS.
Proved.
