What do you need help understanding?
For question 6 I don't understand how to find the perimeter
Where do you need help on this topic?
I am actually going to need help with all of the questions but maybe it will start to make more sense as we go
perimeter is sum of the sides when 2 lines coming from point outside circle both are tangent to circle, then 2 lines are of equal length ex: 2 lines coming from A are both length 2 2 lines coming from B both length 5 2 lines coming from C are both 3
oooh I thought that whole side was 5
yeah they could have labeled it better
Question 6, I believe the perimeter to be 20. Here is how... The measurements given are from the tangent to the vertex of the triangle Two tangents from a point outside of the circle are equal. Therefore AB = 7 AC = 5 and BC = 8 Now just add
Okay so for question 7 do I use
gian better explanation than mine :)
9 is 90 degrees right?
OK here's how... Call radius r So root 28 squared minus root 5 squared is equal to r squared. Therefore 28 - 25 = 3 = r squared. taking square roots r = root 3
thanks :) that is what I got
yes 9 is 90 degrees
I am stuck on number 10 though...
OH never mind I read the question wrong
ED is half of CD
For question 12 how would I find x? Do I assume that x is half of 9?
Also for question 13 how would I find y?
You do not have to assume, those line hatches on the chord tell you it is broken in two halves.
