Answer:
Long = 6√3
Step-by-step explanation:
Reference angle = 30°
Hypotenuse = 12
Long = Adjacent = ?
Apply CAH:
Cos 30 = Adj/Hyp
Cos 30 = Long/12
12*cos 30 = Long
12*√3/2 = long (cos 30 = √3/2)
6√3 = long
Long = 6√3
Answer:
y = -4x + 6
Step-by-step explanation:
3y + 12x = 18
3y = 18 - 12x
y = 6 - 4x
Best of Luck!
Answer:
8.9 = z
Step-by-step explanation:
11 = 2.1 + z - subtract the 2.1 from the 11
Step-by-step explanation:
3x -20= -2x +10
or,5x=30
or,X=30/5
or,X=6
Y= -2×6 + 10
= -2
therefore solution is (6, -2)
