Question

fine the x value.
please tell right answer​

Answer 1

Answer:

2x+x+90°=180° (Angle sum property)

3x=180°-90°

x=90°/3

x=30°

Answer 2

Step-by-step explanation:

1st angle + 2nd angle + 3rd angle = 180

(because of the interior angle property of triangle)

90° + x + 2x = 180

90° + 3x = 180

3x = 180-90

3x = 90

x = 90/3

x = 30°

2x = 60°
