Question

///what is angle CAD

Answer 1

the angle of CAD is 100°

Explanation:

all of the angles inside of the triangle should add up to 180°

so 180=x+80+20, which equals 80°

the angle of a straight line is 180° so use the inside angle of the triangle 80°

180=x+80, now the angle CAD equals 100°

Answer 2

Angle (CAD) = 100
Angle BCA have to equal 180.
180 - (angel b) - (angle c) = 80
So angle A is 80.
Now 180(DAB) minus 80(angle A) = 100
Therefore angle (CAD) is 100.
