Remark
Three angles add to 180o.
The smallest angle = x
The middle angle = 2x
The largest angle = 3x
Solve
x + 2x + 3x = 180
6x = 180
x = 180 / 6
x = 30
Answers
The smallest angle is 30
The middle angle is 30*2 = 60
The largest angle is 30*3 = 90
This is a 30 - 60 - 90 right triangle
Y=kx is the direct variation equation
First plug in the x, y values given to find K
18=k(5)
18/5=k
3.6 = k
Use the k and write a new equation.
y=3.6x
Plug in the x value to solve for y.
y = 3.6(11)
y= 39.6
Answer:
1.95
Step-by-step explanation:
hello :
ln (x + 6) – ln (2x – 1) = 1 ...(*)
this expression exist : 2x-1 > 0 and x+6 > 0 means : x> 1/2 and x > -6
hence for : x> 1/2 (*) equivalent to ln((x+6)/(2x-1))= lne.......(1=lne)
(x+6)/(2x-1) = e
x+6 = e(2x-1) means : x+6 = 2ex-e
-x+2ex = e+6
x(2e-1) = e+6
x = (e+6)/(2e-1) =(2.73+6)/(2(2.73)-1) =8.73/4.46 =1.95
The answer of the equation when a is plugged in to the answer is 27.5.
Answer:
t=4/3 or 3/4
Step-by-step explanation:
12t^2-25t+12=0
(3t-4)(4t-3)=0
3t-4=0 or 4t-3=0
t=4/3 or t=3/4
