We have a bilateral triangle with base length 2 and sidelengths x where x is increasing at a rate of 5 units per minute.

Find the rate of change of the side angle teta when x=2.

Step-by-step explanation:

Given :

base length = 2

side lengths = x

dx/dt = 5 unit/min

Determine d∅ / dt  at x = 2

d∅ / dt  at x = 2  =

attached below is a detailed solution

the answer

b. they are parallel and will never intersect.

i think it is c, not positive though
