Three of given <u>lines</u> form a <u>triangle</u> with <u>measures</u> of two <u>interior angles</u>
and ![(2x+10)^{\circ}.](https://tex.z-dn.net/?f=%282x%2B10%29%5E%7B%5Ccirc%7D.)
The angle with measure
is exterior angle of considered triangle.
The measure of exterior angle of triangle is equal to the sum of the measures of two not adjacent interior angles:
![6x+1=2x+10+79,\\ \\6x+1=2x+89,\\ \\6x-2x=89-1,\\ \\4x=88,\\ \\x=22^{\circ}.](https://tex.z-dn.net/?f=6x%2B1%3D2x%2B10%2B79%2C%5C%5C%20%5C%5C6x%2B1%3D2x%2B89%2C%5C%5C%20%5C%5C6x-2x%3D89-1%2C%5C%5C%20%5C%5C4x%3D88%2C%5C%5C%20%5C%5Cx%3D22%5E%7B%5Ccirc%7D.)
Answer: correct choice is D
A rational number is a number that can be written in form a/b where a and b are integers and b is not eual to 0
simplify eacy
![\sqrt{8}=2\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B8%7D%3D2%5Csqrt%7B2%7D)
![\sqrt{16}=4](https://tex.z-dn.net/?f=%5Csqrt%7B16%7D%3D4)
we get
![\frac{2\sqrt{2}}{3}+4](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Csqrt%7B2%7D%7D%7B3%7D%2B4)
![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
is irrational
since we can't write
![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
as a rational number, the entire phrase is irrational
anwer is irrational
Answer:
The classes need to raise $164.86 more to reach their goal of $1200.
Step-by-step explanation:
$1,200 total
Mrs. LeBlanc's class has raised 50% of the total, so they've raised $600.
1200/2 = 600
Mr. Patel's class has raised $235.14.
235.14 + 600 = 835.14
Ms. Warner's class has raised 1/3 of the total of Mrs. LeBlanc's class ($600), so they've raised $200.
600/3 = 200
835.14 + 200 = 1035.14
The three classes have raised a combined total of $1035.14.
1200 - 1035.14 = 164.86
The classes need to raise $164.86 more to reach their goal of $1200.
Answer:
A chord
Step-by-step explanation:
By the definition of a chord, it is a line segment whose endpoints lie on the circle, (and in this case circle is meant by the set of points equidistant from a center point, or as an algebraic term: circumference)
