Answer:
184
Step-by-step explanation:
The sqrt(144) = 12
14^2 = 196
196 - 12 - 184
Step-by-step explanation:
WX is parallel to YZ and WZ is also parallel to XY
For perpendicular lines, the slopes are negative reciprocals of one another. Therefore, the slope of QC = 3/2
Using this into the formula of slope:
3/2 = (y + 6) / (-1 + 3)
y = -9
If the slope of CD is 2/3, then y works out to be -3.
