Question

In the given figure, find the measure of 21, 22, 23.
1360
104°​

Answer 1

Answer:

1+2 = 136° ( exterior angle is equal to sum of opposite interior angle)

similarly,

1+3 = 104°

3 = 180-136 = 44°

1 = 104-44 = 60°

2 = 136-60 = 76°

(Mark as brainlist)

Answer 2

Answer:

angle 3=44 degrees

angle 2=76 degrees

angle 1=60 degrees

Step-by-step explanation:

angle 3=180-136 degrees              (Linear pair)

so, angle 3=44 degrees

angle 2=180-104 degrees             (Linear pair)

so,angle 2=76 degrees

angle 1=180-(44+76) degrees         (Angle sum property of a triangle)

so,angle 1=60 degrees
