Question

please solve this question step by step ​

Answer 1

Answer:

angle sum property is to be used here,

sum of all the interior angles of a triangle is 180°

so,90°+2x+x=180°

3x=180°-90°

3x=90°

x=30°

so, the angles are 30° and 60°.

Answer 2

Answer:

angle 1= 90° •°• 180°- 2x + x + 90°

=180° = 3x + 90°

= 180° - 90° = 3x

= 90° = 3x

= x= 90/3

= x= 30°

so 1 angle = 30° and 2nd angle = 60° and 3rd angle = 90°
