Answer:

Step-by-step 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
