You take $18.80 divide by 2 =$9.40 then $18.80+$9.40=$28.20
$28.20 x's 5.5=$$155.10
$18.80 x's 40=$752.00
<span>then add 752.00+155.10=$907.10</span>

Answer:
A) 63.43°
Step-by-step explanation:
The two vectors in polar form are ...
u = (√(9²+6²))∠arctan(-6/9) = √117∠-33.69°
v = (√(7²+4²))∠arctan(4/7) = √65∠29.74°
The angle between the two vectors is ...
29.74° -(-33.69°) = 63.49°
