Problem 3 Given an isosceles triangle ABC with AB = AC, D is a point on AB such

that AD: DB = 3:1, E is a point on side AC, and when DE and BC

are extended, they meet at a point F, such that DE: EF = 1:3.

(a) Find the ratio AD: AE.

(b) If ABDF is also isosceles, find the ratio DE : BC.

List the sides of δrst in in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12°

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
