Solve by completing the square:

x² + 16x + 64 = 13 + 64
(x + 8)² = 77
x + 8 = +/- √77

x = - 8 +/- √77

OR

x = - 8 - √77, - 8 + √77

Prove that angles opposite to equal sides of an isosceles triangle are equal.
ZanzabumX [31]

Answer:

Step-by-step explanation:

Take a triangle ABC, in which AB=AC.

Construct AP bisector of angle A meeting BC at P.

In ∆ABP and ∆ACP

AP=AP[common]

AB=AC[given]

angle BAP=angle CAP[by construction]

Therefore, ∆ABP congurent ∆ACP[S.A.S]

This implies, angle ABP=angleACP[C.P.C.T]
