I WILL MARK BRAINLIEST PLEASE HELP FIND ANGLE DEB

ITS DUE AT 12 PLEASE HELP PLEASE

Step-by-step explanation:

We want to find angle DEB. We know AB is perpendicular to AC, CD is congruent to CE and angle B is 48 degrees.

ABC is a triangle. The angles in a triangle must add up to 180 degrees. Therefore:

We know two angles: ∠B= 48° and ∠A= 90° (the little square denotes a right angle).

Note that angle C is part of another triangle. It is isosceles because the two legs (CD and CE) are congruent. Therefore, the two base angles (E and D) are congruent.

∠D and ∠E equal 69 degrees.

Angle CED (∠E)  and DEB are on a straight line together. Therefore, they are supplementary and equal 180 degrees.

Angle DEB is equal to 111 degrees

1/3 + 1/5 = 8/15.
