In the equilateral triangle ABC, D and E are the points on AB and BC respectively, and ab = be, AE and CD intersect at P, CF and are perpendicular to Ae
1. To verify the degree of ∠ CPE
2. Verification: pf = 1-2pc
Your title is wrong. It should be ad = be
1. Because ad = be, ab = AC, ∠ Abe = ∠ CAD = 60
So triangle Abe ≌ triangle CAD,
Therefore, BAE = ACD
Because ∠ BAE + ∠ cap = ∠ BAC = 60
Therefore, ACD + cap = 60
Because in the triangle APC, ∠ CPE is the outer angle
Therefore, CPE = ACD + cap = 60
2. And because CF is perpendicular to AE,
So in right triangle CPF, PF = PC * cos ∠ CPE = 1 / 2pc

If a, B (a is not equal to b) is the root of the equation x square + x-2009 = 0, then the square of a - B =?
A-2009 = 0
a²=2009-a
According to Weida's theorem, a + B = - 1
a²-b=2009-a-b=2009-﹙a+b﹚=2009-﹙﹣1﹚=2010.

When the side length of a square increases by 3cm, its area increases by 39cm2. The side length of the square is ()
A. 5cmB. 6cmC. 8cmD. 10cm
Let the original side length of the square be x, then x2 + 39 = (x + 3) 2, the solution is x = 5, so a
