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

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest

2,600 divided by 80 = 32.5
