Question

Determine the value of x for which r is parallel to s if m angle 1 = 60-2x and m angle 2=70-4x

Answer 1

Answer:

$x=5$

Step-by-step explanation:

$m\angle1=60-2x$ and $m\angle2=70-4x$ are corresponding angles.

Since corresponding angles are congruent, we have

$70-4x=60-2x$

Group similar terms to get;

$70-60=-2x+4x$

$10=2x$

$5=x$
