Line f has a slope of -9/2. line g is perpendicular to f what is the slope of line g​
xxTIMURxx [149]

Answer:

The slope of line g is \frac{2}{9}.  

Step-by-step explanation:

We know that line f has a slope of -\frac{9}{2} and that line g and line f are perpendicular to each other. Perpendicular lines have slopes that are opposite reciprocals of each other. Thus, the opposite reciprocal of  -\frac{9}{2} must be the slope of line g.  

To find the opposite reciprocal of a number, change its sign and swap the numbers of the numerator and the denominator. So, the opposite reciprocal of -\frac{9}{2} must be \frac{2}{9}. \frac{2}{9} has to be the slope of line g as well.

Answer:

  72 feet

Step-by-step explanation:

Triangle JKM is similar to triangle PQM, so we have ...

  JK/KM = PQ/QM

  JK/(60 ft) = (6 ft)/(5 ft)

  JK = (60 ft)(6/5)

  JK = 72 ft

The height of the cliff is 72 feet.
