Answer:
and 
Step-by-step explanation:
Given
Bisector: CD
of Line AB
Required
Apply Pythagoras Theorem
From the question, CD bisects AB and it bisects it at D.
The relationship between AB and CD is given by the attachment
Considering ACD
From the attachment, we have that:



By Pythagoras Theorem, we have

Considering CBD
From the attachment, we have that:



By Pythagoras Theorem, we have:

Mean is equal to sum/ number of values
27+3+2+25+5=62
62/5=12.4
Final answer: D, 12.4 years
Answer:
C!
Step-by-step explanation:
Answer:
UX ≈ 4.5
△UVW = 49.5 ft²
Step-by-step explanation:
[] We can assume that UX is the midline of this triangle.
22 ft / 2 = 11 ft
XW and VX = 11 ft
[] Now that we have 2 sides of a right traingle, we can find the third.
a² + 11² = 12²
a² + 121 = 144
a² = 20
a = about 4.5, which is side UX
[] Since we have all three sides of the triangle, we can also solve for the total triangle's area. To solve for the area of a triangle, we do base times height divided by 2
22 * 4.5 = 99
99 / 2 = 49.5 ft²

First off, I would like to say that you aren't d**b! Always remember that asking for help is never d**b!
To change a fraction to a decimal, put the decimal over its place value. For example, if you had the decimal 0.7, you would put 7 over 10 to create the fraction
.
Lastly, always remember to simplify your answer!
Hope this helps! Have a great day! (:
