Question

Find the measure of 1 and 2 in the below
Figure. The measure of the given two interior opposite
are 20 and 60°​

Answer 1

Answer:

1 = 100 and 2 = 80

Answer 2

angle 1=100° & angle 2=80=

Step-by-step explanation:

Let this be the ∆ABC

In ∆ABC,

angle A+ angle B+ angle C=180°( angle sum property of ∆)

20°+60°+ angle 1=180°

80°+angle 1=180°

angle 1=180°-80°

angle 1=100°

Now, angle 1+angle 2=180° ( linear pair)

100°+angle 2=180°

angle 2= 180°-100°

angle 2=80°
