Question

find the value of a and b

step by step explanation so i can know wth is going on, pls​

Answer 1

If AB || CD

$\angle \: a = \angle \: CBD = 71 \degree$

......Alternate exterior angles or z angles

b° is an exterior angle of ΔCBD

Therefore,

$\angle \: b = \angle \: dcb + \angle \: dbc \\ \\ \angle \: b = 37 + 71 = 108 \degree$
