The altitude and base of a right triangle are in the proportion 3:4. If the base is 20 feet, what is the altitude?
Let x = the altitude in feet. 3 / 4 = x / 20 60 = 4x x = 15 feet
Thus, the altitude is 15 feet.
Check: 15 / 20 = 3 / 4, the correct proportion.

Consider HgSWWSN where the narrow search space in which the nodes form an LL is limited to 1km × 0 . 1km. The node density of sensors in the entire sensor network field is about 500 sensors per square kilometer. If the probability of a WSN node forming an LL is about 0.1, estimate the following: (a) the fraction of time a given node operates its LL in the first round of operation and (b) the number of WSN nodes with LL present in the narrow search space.
