The slope is
(difference in y-values) / (difference in x-values)
= (-4) / (-5)
= 0.8
Let's start with triangle RST. This is a 30-60-90 triangle, which means it has the relationship x - x sqrt(3) - 2x.
If RS is 2 sqrt(3), then ST must be 2 and RT must be 4.
Triangle QRT is a 45-45-90 triangle, which means it has the relationship x - x - x sqrt(2).
If RT is 4, then RQ must also be 4.
Answer: x = 4
Hope this helps!
A carpenter's square is a ruler which looks like a right triangle. Being such, it has a long side and a short side. Assuming that the radius of each wheel is the size of the short side, we can use this to measure the mid point of the wheel. The mid point of the wheel is the optimal point where you can bore a hole.
