Question Description

note that by SSS triangle ABE is congruent to ADE

This means that angle AEB is 90 degrees and angle AED is 90 degrees

since we know that abd is 70, and abe=abd, we see that bae=20 degrees (because it is a triangle and 180-90-70=20)

Using similar reasoning and knowing the triangles are congruent we know that ead is 20

thus bad= 20+20=40!
