Answer:
(d) 60; 210°
Step-by-step explanation:
The factor -3 is equivalent to 3∠180°. The given product is then ...
u = 20∠30°
-3u = (3∠180°)(20∠30°) = (3·20)∠(180°+30°) = 60∠210°
<span>So you need to find the value of x that would make these equal.
2+x = 6+0.5x Subtract 0.5x from both sides.
2+0.5x = 6 Now subtract 2 from both sides.
0.5x = 4 Finally, divide both sides by 0.5
x = 8
So in 8 years, the two trees will be the same height.</span>
