Answer:
14 : 21
Step-by-step explanation:
---> 2:3 ----> 2+3=5
---> Stick's length = 35 inches
<u />
<u>For the first portion</u>
2/5 x 35
2/1 x 7
= 14 inches
<u>For the second portion</u>
3/5 x 35
3/1 x 7
= 21 inches
To confirm: 14 + 21 = 35 inches
14 : 21
Divide both by 7
2 : 3
9:4:5.....added together = 18
9/18 (72) = 648/18 = 36
4/18 (72) = 288/18 = 16
5/18 (72) = 360/18 = 20
so we have 36:16:20
X = 7
y = 10
x + y = 700
7x + 10y = 6400
10x + 10y = 7000
(-) 7x + 10y = 6400
______________
3x = 600
x = 200
200 + y = 700
y = 500
The magnitude of the vector is √(7^2+12^2)=√(49+144)=√193
The direction is α=arctan(y/x)=arctan(12/-7)≈-59.74 however this is relative to the negative x-axis so we add 180° to get the standard angle...180-59.74=120.26°
So the vector is √193 @ 120.26°
