Question

If by=50 °, what is mYAC? The figure is not drawn to scale.

Answer 1

@dan815

Answer 2

see the 2 lines? one is a tangent, namely AC, so, line AC crossing line AB are perpendicular, meaning how many degrees are they making?

Answer 3

90

Answer 4

?

Answer 5

yes, so, notice the 50 degrees one, is inside it, if you SUBSTRACT it from the 90, what's left?

Answer 6

40?

Answer 7

both angles are COMPLEMENTARY angles, so, they both form 90 degrees, if one is 50, the other is the rest, so, yes :)

Answer 8

looks bigger on the picture, because is off scale

Answer 9

ohhh so then would the answer be 40? but i dont see that as an choice

Answer 10

ok, well, is what I get from the picture :|

Answer 11

I'm assuming BY stands for the angle BAY

Answer 12

no its angle yac

Answer 13

these are the choices 130°
80°
65°
100°

Answer 14

well...

Answer 15

your material is saying that "if by = 50\(^o\), so I take that as the angle "bay"

Answer 16

unless is not that

Answer 17

yeah it is

Answer 18

so your not sure on which once it is

Answer 19

well, "by" would only be a vector, a line, not an angle

Answer 20

if measure BY=50, what is measure YAC

Answer 21

thats what the question says

Answer 22

heh, ok, lemme recheck then

Answer 23

kk

Answer 24

I don't see it from that, unless is trig, which I don't think it's

Answer 25

no its geometry

Answer 26

well, can't say then, seems more data is missing, can't say

Answer 27

well if you cant figure it out its ok could you help me with some more? i have quite a few.

Answer 28
