ABCD is a parallelogram with diagonal AC. If the measure of angle CAB is 24º and the measure of angle ADC is 127°, what is the measure of angle DAC?

We are given that ABCD is a parallelogram with diagonal AC.We have to find the measure of angle DAC. (Alternate interior angle theorem)In triangle ACD(Triangle angles sum property)Substitute the values then we get

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
