Question

Ad intersects the angle bac = 120 such that angle bad is one third of angle dac. What is the measure of angle bad?

Answer 1

Answer:

angle BAD=30 degrees

angle DAC=90 degrees

Step-by-step explanation:

let angle BAD=x

then angle DAC=3x

given that angle BAC=120

and angle BAD +angle DAC=angle BAC

x+3x=120

4x=120

x=120/4

x=30

and 3x=3×30=90

so

angle BAD=30 degrees

angle DAC=90 degrees

hence the answer.
