Triangle a b c extended to both sides from corners a and b. d is a point closer to point a on the extended line. angle c is located on the top. the measure of angle c is 80âº, the measure of ∠ cba is 20âº. what is m∠ cad? a) 20⺠b) 80⺠c) 100⺠d)110âº

Step-by-step explanation:

Triangle A B C extended to both sides from corners A and B. D is a point closer to point A . Angle C is located on the top of the triangle.

The diagram is attached below

In a triangle , external angle = sum of two opposite interior angles

so  

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

probably .5

i can on others if necessary.
