< ABE is the whole angle=measures 2b.
<span>< ABF is a portion of <ABE = measure 7b - 24. </span>
measure of the whole angle and a part of the angle
<span>Angle EBF = Angle ABE - Angle ABF
=</span>7b - 24-2b
=6b-24
hope this helps
Answer:
Step-by-step explanation:
First, we can find the slope of the line.
![m = \frac{y1-y2}{x1-x2}\\m=\frac{9-5}{3-1}\\m = \frac{4}{2}=2\\](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By1-y2%7D%7Bx1-x2%7D%5C%5Cm%3D%5Cfrac%7B9-5%7D%7B3-1%7D%5C%5Cm%20%3D%20%5Cfrac%7B4%7D%7B2%7D%3D2%5C%5C)
Using the
equation, we can solve for b
![9 = 2(3)+b\\9 = 6 + b\\b = 9-6 = 3](https://tex.z-dn.net/?f=9%20%3D%202%283%29%2Bb%5C%5C9%20%3D%206%20%2B%20b%5C%5Cb%20%3D%209-6%20%3D%203)
Let's see if
works
![2(1) + 3 \\2 + 3 = 5\\\\2(3) + 3\\6 + 3 = 9](https://tex.z-dn.net/?f=2%281%29%20%2B%203%20%5C%5C2%20%2B%203%20%3D%205%5C%5C%5C%5C2%283%29%20%2B%203%5C%5C6%20%2B%203%20%3D%209)
It checks out!
10(32-n) if you need it simplified then 320 - 10n
Answer:
What is the length of altitude of an equilateral triangle of side 8?
AD = √48 = 4√3 cm. Hence, the altitude of an equilateral triangle is 4√3 cm.
The mean of a set of numbers is the sum divided by the number of terms.
The mean is 6
