Question

alguien me ayuda? xd​

Answer 1

Respuesta:

1. a= x

b= 2x

2x+2x+x+X = 360

6x = 360

x= 60°

a= 60°

b= 120°

2.

a= b = e=x

3x-6 = c

d= f

3x-6 + x = 180°

4x = 174

x= 43.5°

a = b = e = 43.5°

c = 124.5°

d = f = 136.5°

3.

3X- 20 + 2X= 180

5X=200

X= 40

3X-20= C

C= 100°

a =b= 80°

d=f= 100°

2x=e

80°= e

4.

43 + 43 + a+c = 360

a+c= 274

b=43°

a=c = 137°

y yaaaa
