Question

find the value of x for which r || s. then find m∠1 and m∠2.
m∠1 = 72 - 2x
m∠2 = 84 - 3x
the value of x for which r || s is 12.
m∠1 = □

Explanation:

Step1: Substitute \(x = 12\) into \(m\angle1=72 - 2x\)

Substitute \(x = 12\) into the formula \(m\angle1=72 - 2x\).

Step2: Calculate the value of \(m\angle1\)

First, calculate \(2\times12 = 24\). Then, \(72-24=48\).

Answer:

\(m\angle1 = 48\)
