Answer: y=4
Step-by-step explanation:
We have a khown angle wich is 30 degree .
Cos 30 = root square of 3 /2
So root sqaure of 3/2 = 4 root square 3 / x
X= 4 r.sq 3 / r.sq 3/2 = 8
So we just need to apply the pythagorian theorem
X^2= y^2+ 48
64 = y^2 +48
Y^2 = 16
Y=4
Answer:
1+2+3+4+5+7+8+8+8

Answer:
GFC = 4
Step-by-step explanation:
Factors of 20 1 2 <u> 4 </u>5 10 20
Factors of 36 1 2 3<u> 4 </u>6 9 12 18 36
Y - y1 = m(x - x1)
m = -2 (1, -5)
y - (-5) = -2(x - (-5)
y + 5 = -2(x + 5)
y + 5 = -2x - 10
y = -2x - 15 <<< answer
hope this helps, God bless!
Answer:
x=6
Step-by-step explanation:
To solve, we need to get the variable, x, by itself. To do this, first, move all the variables to one side of the equation, and the numbers to the other
2/3(15x-6)=8(x+1)
First, distribute the 2/3 on the left
2/3*15x + 2/3*-6=8(x+1)
10x-4=8(x+1)
Next, distribute the 8 on the right
10x-4=8*x + 8*1
10x-4=8x+8
Subtract 8x from both sides
10x-8x-4=8x-8x+8
2x-4=8
Add 4 to both sides
2x-4+4=8+4
2x=12
Now all the numbers are on one side, and the variables are on the other. x is not by itself though, it is being multiplied by 2. To undo this, divide both sides by 2
2x/2=12/2
x=6
