Answer:
67.5 degrees
Step-by-step explanation:
The first angle is 45 and the second angle is x and the third angle is x (the second and third are equal)
We know the 3 angles of a triangle add to 180 degrees
45+x+x = 180
Combine like terms
45+2x=180
Subtract 45 from each side
45-45 +2x = 180-45
2x= 135
Divide by 2
on each side
2x/2 =135/2
x = 67.5
The position of the fly is shown as cross in the diagram below
The distance of the fly from the ceiling is given as
We need to work out the distance

to be able to work out the value of

by the Pythagoras theorem



by Pythagoras theorem


The distance of the fly from the point P is 4m
Well just think about it don't think about it to much just think it as like 4th grade algebra but bigger numbers witch didn't work for me
