The 105 per hour mechanic worked for 10 hours and the other worked for 15. here's the math.
Since you want to use the SAS theorem, you must find sides that are either side of angles BAC and DAE. You have already made use of sides AE and AC, so the other sides you need to choose are AB and AD. The appropriate relationship for similarity is ...
... AD = 2AB
since you want the sides of triangle ADE to be twice then length of those in triangle ABC.
Answer: # 15 is x=-12 and #16 is x=24
Step-by-step explanation:
The missing length is 12km (i never promised anything xd)
