Question

Please Help! Very Urgent, i only have like half a hour. 20 points and brainiliest.

Answer 1

1; they are similar cause they both have right angles. 2; the same distance as DE.

Answer 2

Yes, they are similar.

`AB\approx 127.3947`

Explanation:

Part 1)

Yes.

First, ∠D and ∠B are both right angles, so they are congruent.

Next, ∠DCE and ∠BCA are vertical angles. So, their measures are congruent.

Then by Angle-Angle Similarity, we acquire:

`\Delta EDC\sim \Delta ABC`

Part 2)

The corresponding sides of similar triangles are proportional.

Therefore:

`\displaystyle (DE)/(DC)=(AB)/(BC)`

By substitution:

`\displaystyle (103)/(76)=(AB)/(94)`

Cross-multiply:

`76AB=9682`

So:

`AB=9682/76\approx127.3947`
