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

angles in a triangle add up to 180 degrees

therefore: angle A+ angle B +angle c=180 degrees

anlgle A=180-angle B +angle C

angle A=180-(130+20)

angle A=180-150

angle A=30 degrees

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