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 = 48
m∠2 = □

Explanation:

Step1: Substitute \(x = 12\) into \(m\angle2=84 - 3x\)

$$m\angle2=84-3\times12$$

Step2: Calculate the value

First, calculate \(3\times12 = 36\). Then, \(84-36=48\).

Answer:

\(48\)
