Answer:
7 hrs
Step-by-step explanation:
formula :- speed=distance/time
speed= 96kph
distance= 672 km
time=?
S=D/T
96=672/T
(cross multiply)
96T = 672
T = 672/96
T = 7 hrs
There are 2 triangles here. You have to drop an altitude and determine the length of it. You can use the fact that sin45 = h/5 (h is the height) and get that the height is 3.5. The rule then is if h is smaller than b which is in turn smaller than c, you have 2 triangles. This is the case of the ambiguous triangle, that SSA that you cannot use to prove congruency. The rules are very particular for whether or not 0, 1, or 2 triangles exist. Learn them.
