Answer 2

How di yo get 28 for the first question?

Answer 3

I sort of guessed it

Answer 4

Well you need to try and calculate it using the Pythagorean Theorem for three axis.

D = sqrt [ (x2-x1)^2 + (y2-y1)^2 + (z2-z1)^2]

Answer 5

so would it be 18?

Answer 6

hint:
for question #2, we can apply the theorem of tangent and secant line of a circle. So we can write the subsequent proportion:
\[x:10 = 10:\left( {x + 15} \right)\]
where \(x=AB\)
