Answer:
So, BC = 5.6 cm
Step-by-step explanation:
Since its a right angled triangle,
taking 62 as reference angle,
cos62 = b/h
or, cos62 = AB/BC
or, cos62 = AB/12cm
or, cos62×12cm = BC
so, BC = 5.63

Step-by-step explanation:
Answer:
a) 
b) 12.72 units
Step-by-step explanation:
Recall that the sine and cosine are completed functions.
This means that: 


Recall that: sine ratio is opposite/hypotenuse

This implies that:





so it takes 2.6 of hours which is the same as 2 hours and 36 minutes for them to reach eachother.
