Answer 1

Respuesta:

3)

$\alpha = 160$

4

$\beta = 60$

5) b= 65

6)Complemento de alfa = 45

Explicación paso a paso:

3)

$a + \alpha = 180......(1)$

7a +20 + a = 180

8a =180 -20

8a = 160

a = 160/8=20

En (1):

$20 + \alpha = 180$

$\alpha = 180 - 20 = 160$

4)

$\beta + 3x = 180.....(1)$

$160 - x = 3x$

$160 = 3x + x$

$160 = 4x$

$\frac{160}{4} = x = 40$

En (1):

$\beta + 3(40) = 180$

$\beta = 180 - 120$

$\beta = 60$

5)

3x + 16 = X + 82

3x - x = 82 - 16

2x = 66

X = 66/2 = 33

b + x + 82 = 180

b +33+82=180

b+115=180

b= 180-115=65

2@ -21 =114-@

2@+@=114+21

3@=135

@=135/3=45

Complemento de@= 90-45=45
