Answer by longjonsilver(155): please explain what "measurement of arc acd = 200 degrees" means since an arc will have a length, not an angle, so which angle do you mean?

Let me restate the problem as it was originally presented. The notes above are my interpertation of the problem. Hope this helps.
A circle with two secants that have a common end point that is outside of the circle. the end point is named p, the top secant is abp and the bottom secant is named cdp, ab and cd are congruent, the measurment of acd is 200 dedrees, so is cab.

Question 6918: Ajax High School is putting a fence around the football field. The distance between the field and the fence is going to be 60 feet on end zone side and 45 feet on the sideline. How many feet of fence will be needed? The football field measures 360 ft by 150 ft. Do I use P=2l+2w (720+300)? and what does the distance between field and fence have to do with the problem? Thanks, Sandy

Question 13762: In a right-angled triangle, the two sides that form the right angle are both 5 inches. Calculate the length of the other side(the hypotenuse)
solution
let the hypotenuse be x
then accourding to phytagorus(may be the spelling is wroung)theorum for rightangle triangle
we have
(hyp)^2=(base)^2+(per)^2
so
(x)^2=(5)^2+(5)^2
(x)^2=25+25
(x)^2=50
x=(50)^1/2 answer

Question 23633: I am trying to solve some challenge problems regarding perpendicular distances.. and I just cannot seem to make any sense of this one:
Calculate the perpendicular distance from A(2,3,-1) to the plane 2x + y - 2z + 9 = 0 using the following method.
By inspection, determine the coordinates of any point C on the plane. Calculate the projection AC projected onto n, where n is the normal vector to the plane. Calculate the magnitude of AC projected onto n.

Question 23753: A triangle has vertices A(-1,k) B(6,k-1) and C(2,-1) where k is a positive number.
(a) Calculate the gradient of AB (My answer was -1/7)
(b) Find expressions for the gradient of:
(i) AC - I got (-1-k)/3
(ii) BC - I got k/4
(c)Find the value of k for which angle ACB + 90 degrees
( I know that m1m2 = -1, but I keep getting a negative answer for k)
Your help is very much appreciated!
