Answer 1

Answer:

Step-by-step explanation:

x = 30

y = 30

z = 120

Answer 2

Answer:

2x +90+x= 180. ( sum of angles on a straight line i.e.AB)

=> 3x + 90 = 180

=> 3x = 180-90

=> 3x = 90

$= > x = \frac{90}{3}$

=> x = 30°

and 2x will be 60 °

now ,

we can find the value of y by the same method,

90+x+y=180

=> 90+30+y=180°

=> 120 + y = 180

=> y = 180- 120

=> y=60°

Alternatively: 2x = y ( vertically opposite angles)

then ,

2x+90+x+y+z=360(sum of angles around a point = 360°)

60+90+30+60+z=360

=> 240 + z = 360

=> z = 360-240

=> z = 120°

Answer. Therefore x is 30°, y is 60° and z is 120°.
