In the diagram below, quadrilateral BAED is a parallelogram, and BD = BC. If angle DBC = $$38^\circ$$, then find angle EAB, in degrees. Apr 14, 2022

We see that since BDC is an isosceles triangle, so, therefore, angle BDC = angle BCD = x.

38 + 2x = 180

2x = 142

x = 71

From here, we see that angle EDB = 180 - 71 = 109

Here's another way to solve it. Because $$\triangle{BCD}$$ is isosceles, $$\angle D = \angle C = 71$$

Because $$BAED$$ is a parallelogram, $$\angle D = \angle E = 71$$

Extend Point A to M, so it is perpendicular to $$\overline {EC}$$ .

$$\angle A = \angle{EAM} + \angle {MAB}$$

In triangle $$\triangle {AME}$$$$\angle EAM = 19$$

Because $$\overline {AM}$$ is perpendicular to $$\overline{BA}$$$$\angle{MAB} = 90$$

Thus, $$\angle A = 90 + 19 = \color{brown}\boxed{109}$$
