Question

If AABC = ADEC, ZB = 5x and ZE = 45° А D с B E x = [?]

Answer 1

Answer:

x=9

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:

∠$B=$∠$E$

Substitute values:

$5x=45$

Solve for x. Divide both sides by 5:

$\frac{5x}{5}=\frac{45}{5}\\\\ x=9$

So, when ΔABC≅ΔDEC, and ∠B=5x and ∠E=45°, the value of x is 9.
