Geometria alguem ?hmm ??

Answer 1

a) •105°+X=180°
X=180°-105°
X=75°

•105°+Y=180°
Y=180°-105°
Y=75°

b) •90°+2x+3x-10°=180°
2x+3x=180°-90°+10°
5x=100°
x=100°÷5
x=20°

• y+90°+2x=180°
y=180°-90°-2x
y=90°-40°
y=50°

•2x=2×20°=40°

Answer 2

Resposta:

a) •105°+X=180°

X=180°-105°

X=75°

•105°+Y=180°

Y=180°-105°

Y=75°

b) •90°+2x+3x-10°=180°

2x+3x=180°-90°+10°

5x=100°

x=100°÷5

x=20°

• y+90°+2x=180°

y=180°-90°-2x

y=90°-40°

y=50°

•2x=2×20°=40°
