Answer:
(a) see attached
(b) CD = 29
Step-by-step explanation:
<h3>(a) </h3>
See the attachment for a diagram.
In the diagram, we have shown point E on the plane so that BE is parallel to AC.

<h3>(b)</h3>
Triangle BDE is a right triangle with hypotenuse BD = 25 and leg BE = AC = 15. The length DE is given by the Pythagorean theorem as ...
DE = √(BD^2 -BE^2) = √(625 -225) = 20
Triangle CDE is a right triangle with hypotenuse CD and legs CE = 21 and DE = 20. The length of the hypotenuse is also given by the Pythagorean theorem as ...
CD = √(CE^2 +DE^2) = √(21^2 +20^2) = √841
CD = 29
To be honest in my opinion, without offending anyone or being condescending, and without triggering anyone, I just want to say I got nothing to say but I have none

Answer:
AB = 4
Step-by-step explanation:
Calculate AB using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(6, 2) and (x₂, y₂ ) = B(0, 10)
AB = 
= 
= 
=
= 4

A: 25.12 (26 if your rounding)
B: You have to multiply R by 2 then by pi (3.14)
C: 10.5 (11 if your rounding)
Step-by-step explanation:
For a: A circle's circumference is its diameter multiplied by pi (3.14) To get the diameter you would multiple the radius by 2. Therefore your answer being 25.12 (Round to 26 if you want)
For c: Divide 65 by pi then that answer by two.
