Question

In the given figure, if
1 = 30°, find 2 and 3.​

Answer 1

Answer:

/_ 1 = 30° ----(given)

therefore, /_1 + /_2 = 180° ----(linear pair)

, 30° + /_2 = 180°

, /_2 = 180° — 30°

, /_2 = 150°

& also

/_1 = /_3 = 30°---(virtically opposite angles)

therefore,

/_3 = 30°

Step-by-step explanation:

Answer 2

Answer:

angle 2 = 150°

angle 3=30 °

Step-by-step explanation:

given angle 1 =30°

to find 2 and 3.

angle 3=30 ° (vertically opposite angle)

angle 2 + angle 3 =180°(linear pair )

angle 2 + 30°=180°

angle 2=180°-30°

angle 2 = 150°
