Given: BD is a diameter m 1 = 100°m BC = 30°
m DAB = ? degrees

Given: BD is a diameter m 1 = 100°m BC = 30°
m ADB = ? degrees

Answer 1

I have no idea what BD and BC signify. I assume that m signifies meters and º indicates degrees, but it is unclear how they go together.

If you want to designate exponents online, use "^", x^2 = x squared.
