AB is a diameter of a circle of radius 1 unit CD is a chord perpendicular to AB that cuts Ab at E If the arc CAD is 2/3 of the circumference of the circle what is the length of the segment AE.?
Hmmm, I got a different answer . . .
is a diameter of a circle of radius 1 unit.
is a chord perpendicular to that cuts at .
If the arc is 2/3 of the circumference of the circle,
what is the length of the segment ?
Of course you made a sketch, right?Code:* * * C * * * / | * * 1/ | * / | * 1 /60° | * A * - - - - * - - + - * B * O\ |E * \ | * 1\ | * * \ | * * * * * * D
Since major arc
. . then minor arc and central angle
Right triangle has acute angle and
