Question

ABC is a triangle with side BC produced to BD. CE is drawn parallel to BA. Find x, y, and z. ​

Answer 1

Answer:

x = 77°

y= 77°

z = 55°

Step-by-step explanation:

In triangle ABC

<A +< B + < C = 180°

<A = 180 - (<B + < C)

<A = 180° - (55° + 48°)

<A = 180° - 103°

<A = 77°

x = 77°.

x = y = 77° (alt. int. angles)

<B = z = 55° (given in fig. by colour)
