Question

find the unknown marked angles in the given figure
pls tell by step by step explanation ​

Answer 1

Answer:

30° + x + angle 1 = 180° (Angle Sum Property of ∆)

Angle 1 = 180° - 110° ( Linear pair)

= 70°

30° + 70° + x = 180°

100° + x = 180°

x = 180°/110°

= 80°

hope it will help :)

Answer 2

Answer:

x = 80 degrees

Step-by-step explanation:

by angle sum property

30 + x + y = 180

30+ x + (180-110) =180 (linear pair)

30+x+70 =180

x +100 =180

x = 80 degrees
