Answer:

A) 10.7a - 8.1b

Step-by-step explanation:

(14.2a + 9.8b) - (13.1b - 0.2a) - (3.7a + 4.8b)

Combine like terms.

(14.2a + 0.2a - 3.7a) = 10.7a

(9.8b - 13.1b - 4.8b) = -8.1b

check the picture below.

now, if we split that triangle like so with that red line, we can use the right-triangle there, to get θ.

$\bf tan(\theta )=\cfrac{\stackrel{opposite}{3}}{\stackrel{adjacent}{3}}\implies tan(\theta )=1\implies tan^{-1}(\theta )=tan^{-1}(1)\implies \measuredangle \theta =\cfrac{\pi }{4}$
