Question

please solve the above problem. Thanks in advance

Answer 1

CD is a line so 110+<2=180
<2=70*
We know sum of angle of a triangle is 180
<1=50
Similarly u can find angle 4 and then<3
Hope it help u

Answer 2

4 + 110= 180 ........(linear angle )
= 4 = 180 - 110
= 4= 70
30+ 3 + 70 = 180.........( the measure of all angles of triangle )
= 3= 180- 110
= 3 = 70
110 + 2= 180........(linear angle )
= 2= 180-110
=2= 70
60+ 70+ 1= 180.......(the measure of all angle of triangle)
=130+1 = 180
= 1 = 180-130
= 1 = 50
