Question

if ∠efg and ∠lmn are a linear pair, and m∠efg is equal to 134°, then what is m∠lmn? m∠lmn = ?°

Explanation:

Step1: Recall linear - pair property

Linear - pair angles sum to $180^{\circ}$.
Let $m\angle EFG = 134^{\circ}$ and $m\angle LMN=x$. Then $m\angle EFG + m\angle LMN=180^{\circ}$.

Step2: Solve for $m\angle LMN$

$x = 180 - 134$.
$x = 46$.

Answer:

$46$
