Question

In the given figure, C and D are points on the semicircle and AB is the diameter.
∠BAD = 70° and ∠DBC = 35°. Calculate ∠ABD and ∠BDC.

Answer 1

Answer:

<ABD = 30°, <BDC = 35°.

Step-by-step explanation:

< ADB = 90°,

< ABD = 180° - (90° + 70°) = 30°.

< BCD = 180° - 70° = 110°.

< BDC = 180° - (110 + 35°) = 35°.
