measures 77. What is the measure of start overline, Y, Z, end overline
YZ
?
If the scale factor is 1/4, it means that all corresponding lengths on the image are 1/4 of the original lengths.
Since the measure of Y'Z' is given as 77, the measure of YZ can be found by multiplying it by the scale factor:
YZ = Y'Z' * Scale factor
YZ = 77 * 1/4
YZ = 77/4
Therefore, the measure of YZ is 77/4.
