HELP PLEASE I DONT UNDERSTAND AND NEED TO PASS

1: 80 degrees

Step-by-step explanation:

1:

Angle R is 130

Angle S is 60

Quadrilatural's angles add up to 360

360 - 130 - 60 = 170

In my opinion angle U looks like a right angle so 90 degrees.

170 - 90 = 80

so 80 degrees

go hook jvc hgv cj xk jvc 6756

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
