Answer:
20.6 cm (im pretty sure lol)
Step-by-step explanation:
sine rule:
(ab = x)
13.5/sin41 = x/sin90
13.5sin90/sin41 = x
x = 20.57741667
ab = 20.6cm
3/4 tons = 1500 lbs/pounds
Answer:
1155
Step-by-step explanation:
let the ratio be 4x:11x
4x=420
x=105
11x=11*105
=1155
If xy=0, assume that x and/or y=0
so we already gots factored
therfor
assume
3n-2=0 and 4n+1=0
solve
3n-2=0
3n=2
n=2/3
4n+1=0
4n=-1
n=-1/4
n=2/3 and/or -1/4
A. the first one will give you a perpendicular line to BA
