Answer 1

Respuesta:

d) m = 40°

e) x = 15°

f) v = 40° ; w = 20°

g) x = 19°

h) x = 20°

Explicación:

d) 2m - 30 + 2m + 50 = 180

4m + 20 = 180

4m = 160

m = 40°

e) 6x + 10 + 4x + 20 = 180

10x + 30 = 180

10x = 150

x = 15°

f)

2v - 40 = 40

2v = 80

v = 40

3v + w + 2v - 40 = 180°

3(40) + w + 40 = 180°

120 + w + 40 = 180

w + 160 = 180

w = 20°

g) 4x + 10 + 6x - 20 = 180

10x - 10 = 180

10x = 190

x = 19°

h) 3x - 40 + 90 + 6x - 50 = 180

9x = 180

x = 20°
