me ajudem namoralzinha, preciso disso para hj...

Answer 1

$90 + 90 + a + 20 + a = 360 \\ \\ 2a + 200 = 360 \\ \\ a = \frac{160}{2} \\ \\ a = 80$

$a + b + b + 10 + 90 = 360 \\ \\2b + 80 + 100 = \\ \\ b = \frac{180}{2} \\ \\ b= 90$

$c + b + 90 + (180 - (a + 20)) = 360 \\ \\ c + 90 + 90 + (180 - (80 + 20)) = 360 \\ \\ c + 180 + (180 - 100) = 360 \\ \\ c + 180 + 80 = 360 \\ \\ c = 360 - 180 - 80 \\ \\ c = 100$
