True or false:
the sum of the measures of any two angles of a triangle is always greater than the supplement of the third angle.

the sum of the measures of any two consecutive angles of a trapezoid is always greater than the sum of the measures of any pair of base angles.

The answer to the question is

It would take Lalelyn bout 3 hours to run the 18m miles, and it will take her

and x +y+z =18 where x, y, and z are the distannce covered swimming, running and bikinr respectifully

Step-by-step explanation:

To solve the question, we lisrt out the variables as follows

Swimming speed of Lakelyn = 250 yards every 5 minutes or 250×12 = 3000 yards/hour = 1.7 miles/hr

Running speed of Lakelyn = 6 miles/hour

Biking speed = 12 miles/hour

The duration it will take for Lakelyn to run 18 miles is given by

Timee taken to run 18 miles t = (Distance covered)/ (Speed of Lakelyn))

or t = D/S

Substituting the known values of such as

Running speed of Lakelyn = 6 miles/hour

From which we have the time taken  to run 18 miles = 18 miles /(6 miles/hour) = 3 hours

should the 18 miles form part of the triathlon then, we have

and x +y+z =18

Where x, y and z are the distance covered Swimming, Running and Biking respectively
