Answer:
m∠4=160°
m∠6=20°
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
m∠6+m∠4=180° ----> equation A (by consecutive interior angles)
m∠6=(1/8)m∠4 ---> equation B
substitute equation B in equation A
(1/8)m∠4+m∠4=180°
Solve for m∠4
(9/8)m∠4=180°
m∠4=180°(8)/9
m∠4=160°
<em>Find the measure of m∠6</em>
m∠6=(1/8)m∠4
m∠6=(1/8)(160°)=20°
