this question is little difficult

Answer 1

Answer:

230° (option D)

Step-by-step explanation:

given angle OCA = 80°, angle COA = 40° and angle BDO = 70°

from the figure x° = 80° + 40° (exterior angle property)

so, x° = 120°

from the figure angle COA = angle BOD = 40°

now, from the figure y° = 70° + 40° (exterior angle property)

so, y° = 110°

now, x° + y° = 120° + 110°

= 230°(option D)
