Answer:
v = 27°
w = 90°
x = 63°
y = 90°
z = 63°
Step-by-step explanation:
The vertical line is a bisector (given the triangle is isosceles, implied since BC≅BD) which means it splits CD in half and with an angle of 90° on both sides of the bisector. At B it means the angle is also split in half with the result that v is 27°. Similarly x and z are congruent and equal to the remainder when the angle sum of a triangle is subtracted by 90°+27°.
x = z = 180° - (90°+27°) = 63°
