Answer: 
Step-by-step explanation: d is length of a hypotenuse in triangle. Use Pytago theorem d = 
A and b are not true because
Using the Pythagorean theorem we can solve for x.
x^2 + 6^2 = 10^2
Simplify:
x^2 + 36 = 100
Subtract 36 from both sides:
x^2 = 64
x = √64
x = 8
Answer:
x^2+4x-32=0
(mid-term breaking---4 x 8=32)
x^2+8x-4x-32=0
x(x+8)-4(x+8)
x+8=0 or x-4=0
So x=+4 or x=-8
Step-by-step explanation:
Length of the pie = πD
Length of the pie = 10π
One slice = 10π ÷ 6 = 5.25 in (Answer C)
