Question

in the given figure 1 ll m, find the values of a, b, c​

Answer 1

Answer:

a=45 by alternate angles

c=55 same reason above

b=180-a+b by sum rule of triangles

b=180-45+55

b=80

Answer 2

Step-by-step explanation:

HÉRÉ IS YØUR ANSWÉR MÀTE!!

HØPE THÍS HÊLPS YØÛ!!!

angle A= 45°[ alternate interior angles]

angle C= 55° [ Alternate interior angles]

angle A + angle B+ angle C= 180° [Angle sum property of triangle]

45°+ angle B+ 55°=180

100°+ angle B= 180°

angle B= 180-100

angle B= 80°

SO......

ANGLE A= 45°

ANGLE B= 80°

ANGLE C= 55°
