In circle P, what is the measure of arc DAB?

Answer 1

add 128 degrees to 90 degrees and you will get 218

Answer 2

Answer: The measure of arc DAB is 218°.

Explanation:

Since we have given that

∠APD = 128°

and

∠BPD = 90°

So, we need to calculate the measure of arc DAB.

Arc DAB contains two angles :

1) ∠APD

2)∠BPD

So, Sum of both the above angles = Measure of arc DAB

Measure of arc DAB is given by

`128^\circ+90^\circ\\\\=218^\circ`

Hence, the measure of arc DAB is 218°.
