Question

Find
x
in
following
diagrams​

Answer 1

Explanation:

1. angle ABC is equal to 180 degree. angle B is 80° and angle C is 180-140= 40°.. with the help of angle sum property 180- 120= E= x= 60°
2. CEA is equal to 180 degree. so 180-110= 70° with angle sum property 70+45 degree minus 180° is 65°... and V. O. A Angle B=90° x= 90°+65°-180°= 25°
3. angle A is equal to angle C with the help of angle sum property. 70+35-180°= X = 75°
