The friend is wrong - According to the Pythagorean Theorm, if c is the hypotenuse and a and b are opposite sides then c^{2} = a^{2} + b^{2}
if c=65 inches, a=16 inches and b = 63 inches, then
65^{2} =16 ^{2} + 63^{2}
right hand side of the equation = 256 + 3969 = 4225
left hand side of the equation = 65^{2}= 4225
So we see, left hand side = right hand side
Hence the theorm is proved.
Answer is B. 48
By circle theorem, the angle at the centre of the circle is twice the angle at the circumference.
Answer:
x = 
Step-by-step explanation:
Given
Ax + By = C ( subtract By from both sides )
Ax = C - By ( divide both sides by A )
x =
