Question

In the adjoining figure , DE||AB , DEC = 45° and EDC = 35°. Find the values of a and b .​

Answer 1

Answer:

Given, DE|| AB

angle DEC = 45°

angle EDC = 35°

With AB||DE and DB as transversal,

angle DBA = angle BDE (alternate interior angles are equal)

=> a = 35°

With AB||DE and AE as transversal,

angle EAB = angle AED (alternate interior angles)

=> b = 45°

Therefore, a = 35° & b = 45°
