Question

if m∠abd = 110°, and m∠dbc = 35°, then m∠abc = ?°

Explanation:

Step1: Identify angle - addition relationship

$\angle ABC=\angle ABD+\angle DBC$

Step2: Substitute given angle - measures

$\angle ABC = 110^{\circ}+35^{\circ}$

Step3: Calculate the sum

$\angle ABC=145^{\circ}$

Answer:

$145$
