Answer:
i) mAB = mBD (Not True)
Step-by-step explanation:
ii) mAC = mAD , CD is a chord and AB is a diameter. CD⊥AB and hence AC = AD,
Equal chords have equal segments . Hence it is true
iii) ∠BDA = ∠BCA true
iv) ∠PBC = ∠DBA True
Hence the three options are correct except the one.
So our answer is option A mAB = mBD (Not True)

First Question
circumference = pi * diameter
diameter = circumference/pi = 94.2 in./3.14 = 30 in.
The wheels have a 30-inch diameter.
-----------------------------------------------------------------------
Second question
The area of a circle: area = pi * r^2
radius = diameter/2 = 94.2 in./2 = 47.1 in.
area = pi * r^2 = 3.14 * 47.1 in. * 47.1 in. = 6966 in.^2
Answer: 6966 in.^2
-----------------------------------------------------------------------
Third question
The piece of felt has a width equal to the diameter of the wheel. The length has to be the same as 4 diameters.
4 * 94.2 in. = 376.8 in.
Answer: 376.8 in.
Yes the value of X is 12.53 :)
Pythagorean theorem.
11•11=121+6•6=36=157
The square root of 157=12.53
