Question

Find the measures of the unknown angles.

If ∠BAC=∠DBA=∠ACD, find ∠DBA,∠ADB,∠CDA,∠DAC, and ∠ACD.

Answer 1

Answer:

Find the measures of the unknown angles using the angle sum property. ∠BAC=∠ABC=∠ACB ∠DBA= ° ∠ADB= ° ∠ADC= ° ∠DAC= ° ∠DCA= ° ∠A=29°.

Step-by-step explanation:

Find the measures of the unknown angles using the angle sum property. ∠BAC=∠ABC=∠ACB ∠DBA= ° ∠ADB= ° ∠ADC= ° ∠DAC= ° ∠DCA= ° ∠A=29°.

Answer 2

Answer:

Opposite angles of parallelogram are equal.

 ∠DAB=∠BCD=75o  and ∠DBC=60o 

 ∠BDC+∠DBC+∠BCD=180o 

 ∠BDC=180o−∠DBC−∠BCD=180o−75o−60o=45o
