Question

if m∠abm = 92° and m∠mbc = 41°, what is the m∠abc?

Explanation:

Step1: Identify angle - addition relationship

$\angle ABC=\angle ABM+\angle MBC$

Step2: Substitute given values

$\angle ABC = 92^{\circ}+41^{\circ}$

Step3: Calculate the sum

$\angle ABC=133^{\circ}$

Answer:

$133^{\circ}$
