Question

sorry guys for disturbing but its urgent...​

Answer 1

Step-by-step explanation:

You didn't disturb us dear. Its the duty of friends to help each other.

lets consider other angles as x.

so

90+x+x+x=180

90+3x=180

3x=180-90

3x=90

x=30

So, all the other angles measure 30°.

Answer 2

Step-by-step explanation:

let each other three angles of this parallelogram be x .

sum of each angle of parallelogram

= 360°

x + x + x + 90° = 360

3x = 270 => x = 90°

other three angles are 90°,90° & 90° respectively.
