Answer:
BCD= 70°. DAB= 70°.
Step-by-step explanation:
BCD: Let's first look at angle DEB. It's 90° which means that it's vertical opposite side is 90° too. Triangle adds up to 180. 90+20= 110. Which makes angle C as 70°. Now we know the angle of one right angled triangle. (P.S: angle f isn't a right angle please erase that from there). Now, BCD is 70°.
For angle DAB we know that it is an acute angle. The answer will be <90°. Now remember an important thing, it will be 70° because since it's a parallelogram angle DAB is diagonal to angle BCD.
In a parallelogram, when 2 sides are 70 the other two are always 110. A bit like the diagram I have made of this. Now, we have discovered 2 things, angle E is 90 and angle D is 110.
