A triangles interior angles sum is always 180°. So we need to find B. To do that we will add the angles we have, then subtract to find angle B:-

43 + 66 = 109

180 - 109 = 71

Check:-

43 + 66 + 71 = 180

SO, angle B is 71°.

Hope I helped ya☺☺☺

No, the table is not proportional. I know this because when you divide x by y the answer is not the same.

y/x = Unit rate or constant rate

Work : (The numbers that are bold are the quotient of y/x)

85 = 17 79 = 7.9 73 = 3.65 67 = 1.67

5 10 20 40
