I have the fist one BD? But i dont know rest

radar · Answer

GH is 5x -10     You need to find x.  GH = IG or 3x=5x-10

Solving for x we get x=5   so 5x-10 is 5(5)-10=25-10=15

Thank you:)

radar · Answer

Y could be found if the following reasoning makes sense.  Angle ABD equals angle DBC because you state BD is a bisector of angle ABC.  Angle DBC equals angle CBE because they are opposite equal sides of congruent right triangles.  That being the case we can now state;  (8y + 4)degree = 10y degrees solving for y we get 2y = 4 degree, y = 2 degree.

Now with the value of y established, we know angle DBE is 40 degrees, do you see why?

anonymous · Answer

yes i do that helped alot :)

First for the last one I was thinking all we would need to do is to substitute for x and y getting 47 which is a choice, but with further thought x in in a linear distance measurement (maybe cm, in etc) and y is in degrees so you could not just add them.  I don't know how to get the last oner.

It could be a trick question, I don't see a correct answer.
