Answer:
Angle CDE=ABC. (Vertically opposite angles are equal)
hence ,ABC=45°
sum of three angles in a triangle is 180°.
CAB+ABC+ACB=180°
45°+45°+X=180°
90°+X=180°
X=180°-90°
X=90°
Therefore ACB=90°
Hope this will help you.

Given
AB is parllel to DE
Angle EDC = 45⁰
Angle CAB = 45⁰
To Find
Angle ACB =?
solution
Angle B = Angle D = 45⁰
Angle ACB + Angle CBA + Angle BAC = 180⁰. (Angle sum property)
Angle ACB + 45⁰ + 45⁰ = 180⁰
Angle ACB + 90⁰ = 180⁰
Angle ACB = 90⁰
