Question

Please help this is due tomorrow and I don’t know what to do. I keep getting this wrong.

Answer 1

BE=24

Angle EBC=33

Explanation:

Rectangle diagonals are congruent so

`3x + 6 = 6x - 12`

`3x + 18 = 6x`

`18 = 3x`

`x = 6`

Plug that in one of the equations.

`3(6) + 6 = 24`

BE=24.

ECD is apart of Isoceles triangle EDC.

Another isoceles triangle is EAB.

They triangle share two sides( remeber all diag ki bals in a rectangle are congruent) and a angle E, so they are congruent triangles.

That means Angle EBA measures 57 degrees.

Angle EBC and Angle EBA add up to 90 degrees so

Angle EBC=33
