​plz give answer guys.... I request
please

Answer 1

Answer:

1-75°

2-135°

Step-by-step explanation:

180°=45°+x+x+15° (angle sum property of triangle)

180°=60°+2x

180-60=2x

120°=2x

120/2=x

60°=x

a. angle BAC=x+15°

=60+15=75°

b. angle ABE+ angle ABC=180° (linear pair angle)

45°+angle ABE=180°

angle ABE=180-45

=135°
