In the diagram below, DAB and DAC are adjacent angles. If mDAC = 25°, what is mDAB in degrees? What is mBAC in degrees?

Final answer:

Without more information, we cannot determine mDAB or mBAC. However, if DAB and DAC form a straight line, mDAB would be 155 degrees. For mBAC, additional details are necessary to determine its measurement.

Step-by-step explanation:

To find the measure of angle mDAB, we need additional information. Since we are only given the measurement for angle mDAC, and we know that DAB and DAC are adjacent angles, we cannot determine the measurement of mDAB without knowing either their sum or the measurement of angle mBAC.

If by any chance angle DAB and angle DAC form a straight line, then we can assume that the sum of mDAB and mDAC is 180 degrees because the sum of adjacent angles that form a straight line is 180 degrees. Assuming this, we can then calculate mDAB by subtracting mDAC from 180 degrees.

mDAB = 180 degrees - mDAC = 180 degrees - 25 degrees = 155 degrees.

To find mBAC, we would need to know if BAC is part of any of these angles or if additional angles are formed with BAC which we could then use to find its measurement.
