Answer:
logx=120
Step-by-step explanation:
Answer:
![\therefore x=50\°](https://tex.z-dn.net/?f=%5Ctherefore%20x%3D50%5C%C2%B0)
Step-by-step explanation:
Let the angle between
and 150° be = b°
[ Forming a linear pair of angles]
Solving for
by subtracting both sides by 150.
![150+b-150=180-150](https://tex.z-dn.net/?f=150%2Bb-150%3D180-150)
∴ ![b=30\°](https://tex.z-dn.net/?f=b%3D30%5C%C2%B0)
[Angle lying on a straight line add up to 180]
Plugging in ![b=30\°](https://tex.z-dn.net/?f=b%3D30%5C%C2%B0)
![50+2x+30=180\\2x+80=180](https://tex.z-dn.net/?f=50%2B2x%2B30%3D180%5C%5C2x%2B80%3D180)
Solving for
by
subtracting both sides by 80.
![2x+80-80=180-80\\2x=100](https://tex.z-dn.net/?f=2x%2B80-80%3D180-80%5C%5C2x%3D100)
then dividing both sides by 2.
![\frac{2x}{2}=\frac{100}{2}\\\\\therefore x=50\°](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B2%7D%3D%5Cfrac%7B100%7D%7B2%7D%5C%5C%5C%5C%5Ctherefore%20x%3D50%5C%C2%B0)
<span>The answer to this question is True. Apparently, there are a lot of mathematical problems regarding coin and pricing problems can be written with a system of equations.</span>
You can identify an expression by the number of the terms in the expression.
monomial = one term
binomial = two terms
and so on.
![24x^{2}](https://tex.z-dn.net/?f=24x%5E%7B2%7D)
y contains only one term, so it is a monomial.
9q +
![\frac{4q}{5p}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4q%7D%7B5p%7D%20)
-
![3p^{2}](https://tex.z-dn.net/?f=3p%5E%7B2%7D%20)
contains three terms, so it is a trinomial.
