Question

find the value of unknow angles in the following​

Answer 1

Answer:

x+x+90= 180

2x+90= 180

2x= 180-90

2x = 90

x = 90/2

x = 45

Answer 2

Answer:

x= 30°

2x= 60°

Step-by-step explanation:

x+ 2x + 90° = 180° (angle sum property)

3x + 90° = 180°

3x = 180 - 90

= 90

x = 90/ 3

= 30°

2x = 30×2

= 60°
