Answer 1

38, 42 right?

Answer 2

hmm what did you get for angle 1?

Answer 3

yah what did you get for angle 1

Answer 4

im pretty sure 1 is 38

Answer 5

angle 2 would be 180-38=142

Answer 6

but only if angle one is 38

Answer 7

38 and 42 makes them "complementary angles"

but 1 and 2 are colinear, and thus "supplementary angles"

Answer 8

for angle 1 i did \[\angle= (arc1+arc2)/2\]

Answer 9

The rule is that angle 1 wouldd be equal to half the sum of the 36 and the 40. 36+40=76. 76/2=38. So angle 1 is 38, and angle 2 is 180-38=142

Answer 10

actaully... not even you'd need 2 to be 52 to be complementary.. anyhow.... notice
1 and 2 are supplementary angles

Answer 11

@MVen you're correct, that is 38
but 2 is a supplementary angle to 1
thus they make up 180 degrees, notice the flat line they lie on
