Answer:
17 degrees
Explanation:
<ABD = 25. We know that ABD has a right triangle included. Therefore we know that 25 + 90 + <A = 180.
Therefore 115 + <A = 180.
<A = 65 degrees.
This means that part of <A = 65 degrees. The other part of <A is 44 degrees, add the two to find the whole of angle A.
65 + 44 = 109.
Angle CAD would be congruent to angle C due to alternate interior angles. meaning <C is 44 degrees. Since the angles in a triangle add up to 180 you can write the equation:
109 + 44 + <B = 180.
Combine the like terms.
163 + <B = 180.
Subtract to find angle B.
<B = 17
