Step-by-step explanation:

(i)

Using cos(a - b) = cos a cos b + sin a sin b

$\frac{4}{5}$ = cos a cos b + $\frac{1}{5}$

cos a cos b = $\frac{4}{5} -\frac{1}{5} = \frac{3}{5}$

(ii)

Using cos(a + b) = cos a cos b - sin a sin b

cos(a + b) = $\frac{3}{5}-\frac{1}{5}=\frac{2}{5}$

(iii)

Using cot a = $\frac{cos a}{sin a}$

$=(\frac{cos A}{sin A} )(\frac{cos B}{sin B} )$

$=\frac{cos A cos B}{sin A sin B}$

$=\frac{\frac{3}{5} }{\frac{1}{5} }$ $=\frac{3}{5}$ × $5$

= 3

Write an equation of a line in slope intercept form that is parallel to the line x + 4y = 6 and passes through (-8, 5)

Annette [7]

If the line is parallel, then their slope would be equal.
4y = -x + 6
y = -1/4 x + 3/2

Compare it with, y = mx + b
m = -1/4 [ Slope ]

Now, y - y1 = m(x - x1)
y - 5 = -1/4 (x + 8)
y - 5 = -1/4x - 2
y = -1/4x + 3

In short, Your Answer would be: y = -1/4x + 3

Hope this helps!
