Answer:

<u>∠ABC = 39°</u>

Step-by-step explanation:

Since ED bisects ∠CBD :

<u>∠EBD = ∠CBE = 30°</u>

<u />

Now, <u>∠ABD = ∠ABC + ∠CBE + ∠EBD = 99°</u>

Solving :

  • 99° = ∠ABC + 30° + 30°
  • ∠ABC = 99° - 60°
  • <u>∠ABC = 39°</u>

Solve similar triangles (advanced)<br> Solve for x<br> x=?
lesya692 [45]

Answer:

x = 1.2

Step-by-step explanation:

AD/AB = DE/BC (Similarity Theorem)

AD = 6 + 4 = 10

AB = 6

DE = 2

BC = x

Plug in the values

10/6 = 2/x

Cross multiply

10*x = 2*6

10x = 12

Divide both sides by 10

x = 12/10

x = 1.2
