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:

Hey there!!
How do we find the midpoint?
We take the average , the average is =
Sum of the observations / total number of observations
The end points are given as 4 and 11
Sum = 11 + 4
Number of observations = 2
= 15 / 2
= 7.5 is the midpoint
Multiplying all of the numbers together you'd get 320
Answer:
x = 31
Step-by-step explanation:
Given:
MN = 20
PQ = x
RS = 42
Required:
Value of x
SOLUTION:
In a trapezoid, the midsegment length equals the sum of both bases divided by 2
This implies that:
PQ = ½(MN + RS)
Plug in the values
x = ½(20 + 42)
x = ½(62)
x = 31
