given AB and AD are tangents of C, and the m<BDC=45degrees what is the measurement o <DAB
To find the measurement of angle DAB, we need to use the properties of circles and tangents.
First, let's understand the given information: AB and AD are tangents to the circle at points B and D, respectively. We also know that the angle BDC is 45 degrees.
From the properties of tangents, we can conclude that angle BDC is equal to the angle formed between the tangent and the radius of the circle. Therefore, angle BDC is a right angle (90 degrees).
Since angle BDC is 45 degrees, we can determine that angle DAB is half the measure of angle BDC. Hence, angle DAB would be 45 degrees divided by 2, which equals 22.5 degrees.
Therefore, the measurement of angle DAB is 22.5 degrees.
