Answer:
For the first one:
D) The perpendicular bisector of line MN
For the second one:
You need a protractor (angle ruler) to measure the angle. After finding the measurement, divide it into two. After finding the result, find the point that has that angle.
Example -
The pie measures 120°.
120° ÷ 2 = 60°
Find the point that measures 60° and connect the points (from the start to the edge of the pie).
For the third one:
C) m∠ABD ≅ m∠CBD
Answer:
-2/9
Step-by-step explanation:
Add two 0's to 14.7 making 14.700
In the isosceles trapezoid ABCD, draw two perpendiculars AM and BL from A and B to the side CD.
Now, LM = BA = 5 m
CD = CL + LM + MD
= CL + 5 + CL (CL = MD)
= 2CL + 5
But, CD = 11
Therefore, 2CL + 5 = 11
2CL = 11 - 5
= 6
CL = 6/2 = 3m
MD = 3m
Now, consider the right triangle AMD.
We have,
= 
= 16 - 9
= 7
Hence, height of the isosceles trapezoid = AM = 
Y² = 12
y = 2√3
x = √6
Now, 4 /xy
= 4/2√3√6
= 2 / 3√2
= √2/3
In short, Your Answer would be √2 / 3
Hope this helps!
