Answer:
The length of the side PC is 34 cm.
Step-by-step explanation:
We are given that BP is the perpendicular bisector of AC. QC is the perpendicular bisector of BD. AB = BC = CD.
Suppose BP = 16 cm and AD = 90 cm.
As, it is given that AD = 90 cm and the three sides AB = BC = CD.
From the figure it is clear that AD = AB + BC + CD
So, AB = 
= 30 cm
BC = = 30 cm
CD = = 30 cm
Since the triangle, BPC is a right-angled triangle as 
PBC = 90°, so we can use Pythagoras theorem in this triangle to find the length of the side PC.
Now, the Pythagoras theorem states that;
= 1156
PC = 34 cm
Hence, the length of the side PC is 34 cm.
Check the picture below.
now, recall, both blades are congruent, thus a = b, so c² = a² + b² -> c² = b² + b².

Answer:
x = -9
Step-by-step explanation:
Segment NL is twice the length of midsegment WV.
2WV = NL
2(x+15) = x+21
2x +30 = x +21 . . . . simplify
x = -9 . . . . . . . . . . . . add -30-x
_____
<em>Additional comment</em>
This value of x means the other segments are ...
MN = 12
WV = 6
NL = 12
Answer:
4÷68=1/17 is correct answer
Answer:
89
Step-by-step explanation:
85+92+95+81+92=445 and since there are 5 numbers you're going to divide by 5 so 445/5 which is 89
