Question

statement reason 42° + m∠2 = 90° given m∠2 = 48° ??? addition poe angle addition poe substitution poe subtraction poe

Explanation:

Step1: Start with given equation

$42^{\circ}+m\angle2 = 90^{\circ}$

Step2: Isolate $m\angle2$

Subtract $42^{\circ}$ from both sides of the equation using the subtraction property of equality (subtraction POE). So, $m\angle2=90^{\circ}- 42^{\circ}=48^{\circ}$.

Answer:
