Answer:
AC =4DB
Step-by-step explanation:
D is midpoint of AB .So, AD = DB
AB = 2DB ---------- (i)
B is the midpoint of AC.So, AB = BC
AC = 2AB
= 2*2DB {FROM 1}
=4DB
Answer:
<em>x=9</em>
Step-by-step explanation:
If the triangles are congruent, then the angles B and E are also congruent (because they lie in the same place). Set an equation where B is equal to E:
∠∠
Substitute values:
Solve for x. Divide both sides by 5:
So, when ΔABC≅ΔDEC, and ∠B=5x and ∠E=45°, the value of x is 9.
