Answer:

Option C. 119°

Step-by-step explanation:

In the given triangle BCD, ∠DBC = 61° and ∠BDC = 48° are given.

We have to calculate the measure of ∠ ABD.

Since ∠ABD + ∠DBC = 180° [ supplementary angles ]

Therefore ∠ABD + 61° = 180°

∠ABD = 180° - 61°

∠ABD = 119°

We should not get confused with the measures of other angles given.

Option C. 119° is the measure of ∠ ABD
