Thank you for the opportunity to help you with your question!

As sum of angle 1 ,angle 2, and angle 3 is equal to 180, we therefore have:

3 x/10+11 x-4+90=180

x(3/10+11)=90+4

x=940/113

Putting value of x , we have

Angle 1=3x/10=3x(94/113)=282/113

Angle 2=11 x-4=11 x(940/113)-4=9888/113

Angle 3=90

Please let me know if you need any clarification. I'm always happy to answer your questions.
