Question

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

Explanation:

Step1: Identify angle - addition relationship

We know that $\angle ABC=\angle ABD+\angle DBC$.

Step2: Substitute given values

Given $\angle ABD = 110^{\circ}$ and $\angle DBC=35^{\circ}$, so $\angle ABC=110^{\circ}+ 35^{\circ}$.

Step3: Calculate the sum

$110 + 35=145$.

Answer:

$145$
