Question

on the given figure find the angle DBO​

Answer 1

Answer:

c) 80°

Solution:

angle AOC= angle DOB... Vertically opposite angles

:. angle DOB = 30°

angle ACO = angle ODB... Given

:. ∆ AOC = ∆ DOB... AA TEST OF SIMILARITY

angle AOC + angle ACO + angle CAO = 180° ... Angular measure of a triangle is 180°

:. angle DOB + angle OBD + angle ODB = 180°

:. 30° + angle OBD + 70° = 180°

:. angle OBD = 180° - 100°

:. angle DBO Or OBD = 80°
