Answer:
552
Step-by-step explanation:
(8-g)/7/8 = (8-5/6)/(7/8)
= (3/6) x 8/7
= 1/2 x 8/7
= 4/7

Answer:
SEgment AC is congruent to segment AB
Step-by-step explanation:
given is a triangle ABC with a segment joining A to D on side BC.
To prove that ABD is congruent to ACD
Let us compare these two triangles.
AD = AD (reflexive) Thus one side is equal.
IF AB = AC, then by isosceles triangles property we have angle B = angle C
Thus we get two sides equal. But this is a necessary condition not sufficient.
Because to prove congruence we need one more condition either CD = BD or Angle CAD = angle DAB
Thus if either AD is angle bisector, or D is mid point besides AC = AB we get
the two triangles are congruent.
