From the diagram above,
XZ = 10 in and OX = 10 in
we are to find length of OY
XZ is a chord and line OY divides the chord into equal length
Hence, ZY=YX= 5 in
Now we solve the traingle OXY
To find OY we solve using pythagoras theorem
applying values from the triangle above
Therefore,
Length of OY =
Hence, the values of x, y and z are as follows:
x=10
y=5
z=2
Further explanation:
When two triangles are congruent, then their respective sides will also be congruent or equal
As it is given that
ΔABC≅ΔDFE
Which means that
EF = BC
ED=AC
FD=AB
Now,
Hence, the values of x, y and z are as follows:
x=10
y=5
z=2
