Respuesta :

Due to BD is an angle bisector, you have that ∠ADB and ∠DBC are equal.

Then, you have:

7).

m∠ADB = m∠DBC replace by the expressions given in the figure

54 = x - 29 add 29 both sides

54 + 29 = x

83 = x

x = 83

Hence, x is x = 83

9).

3x + 4 = 25 subtract 4 both sides

3x = 25 - 4

3x = 21 divide by 3 both sides

x = 21/3

x = 7

Hence, x is x = 7
