Answer:
Explanation:
m∠2=71° because they are vertical angles so are congruent
those 4 angles in the midle will add up to 360°
∠3+∠5=360-2*71=218 so
m∠3=218/2=109°
m∠5=109°
mostly use that the sum of angles in a Δ add to 180
m∠1=180-47-71=62°
m∠4=180-109-36=35°
m∠6=180-42-109=29°
use that opposide ∠s in a quadrinateral add to 180
m∠7=180-47-35-29= °69
m∠8=180-42-62-36= °40
