Question

Find the measures of the unknown angles using the angle sum property.

∠BAC=∠ABC=∠ACB



∠DBA=
°

∠ADB=
°
∠ADC=
°
∠DAC=
°
∠DCA=
°



∠A=29°

Answer 1

A=29°

and angle B=angle C

using the angle sum property,the sum of all angles of a triangle is equal to 180°

then,

A+B+C=180°

let's the angle b and c be x°

→29°+x+x=180°

→29°+2x=180°

→2x=180°-29°

→x=151°÷2

=75.5°

Answer 2

Answer:

∠DBA= 60°

∠ADB= 91°

∠ADC= 89°

∠DAC= 31°

∠DCA= 60°
