Question

in the figure below, m∠1 = 64° and m∠2 = 79°. find m∠fgj. m∠fgj = 0°

Explanation:

Step1: Identify angle - addition relationship

The measure of $\angle FGI$ is the sum of the measures of $\angle 1$ and $\angle 2$.

Step2: Calculate the measure of $\angle FGI$

$m\angle FGI=m\angle 1 + m\angle 2$. Given $m\angle 1 = 64^{\circ}$ and $m\angle 2=79^{\circ}$, then $m\angle FGI=64^{\circ}+79^{\circ}=143^{\circ}$.

Answer:

$143$
