Since angle is BCD is 36 and ABCD is also. 36, The measure of ZB is known to be 36 degrees.
Angle measurement is known to be the rate or the number of rotation from the start to an endpoint of any given ray.
Note that a triangle is composed of shape that has 3 sides and angles
For the △BCD, based on the fact that the side DB ≅ CD, then the base angles will be said to be the same or equal. This depict that the triangle is known to be an isosceles triangle.
Therefore, since the given triangle m <C = m < D
Based on the fact that ∠CD= 36 degrees an Since angle is BCD is 36 and ABCD is also. 36, The measure of ZB is known to be 36 degrees.
