Since the trout is 4.8m below Jamal and it takes 1.5m just to get to the surface of the water, we will subtract the two numbers.
1.5 - 4.8 = - 3.3 The trout is 3.3 meters below the surface.
Answer:

Step-by-step explanation:
First let's find the value of 'p-q':

To find |p-q| (module of 'p-q'), we can use the formula:

Where 'a' is the coefficient of 'i' and 'b' is the coefficient of 'j'
So we have:

Now, we need to find the module of p and the module of q:

Then, evaluating |p-q|-{|p|-|q|}, we have:

Answer:
AB = 26.5º
Step-by-step explanation:
cosA = adj/hyp
cosA = AC/AB
cos41 = 20/AB
Multiply both sides by AB
AB * cos41 = 20
Divide both sides by cos41
AB = 20/cos41
AB = 26.5º
