Question

use the protractor photo to find the measure of each of the following angles$\ \textless \ abd$

Answer 1

You have to read the protractor to determine the measure of each angle.

For all the angles B is the vectress.

∠ABF =90º

∠ABE= 40º

∠ABD= 20º

∠EBF= ∠ABF-∠ABE= 90º-40º= 50º

∠DBE= ∠ABE-ABD= 40º-20º=20º
