Step-by-step explanation:
SinA=1/3=p/h
p=1,h=3,and b=?
Using Pythagoras Theorem,
b=√3^2-1^2
b=√9-1
b=√8=2√2
Now,
CosA=b/h=2√2/3
TanA=p/b=1/2√2
There is no phi in my keypad so I use A angle instead of phi.Adjust it.
Answer:
The slope is -3
Step-by-step explanation:
Find 2 points (-2,3) (-1,0) are 2.
Next subtract y 1 by y 2 in this example, 3-0 which equals 3
After that, subtract x 1 and x 2. In this example, -2-(-1) which equals -1.
Now dive y over x. 3/-1 or -3.
So the slope is -3.
Answer:
The length of the side of a square is
Step-by-step explanation:
Area of square =
We need to find length of the side
The formula used will be:
Putting value of area of square, we can find length
So, length of the side of a square is
There's no problem so we can't answer it
Answer:
$9.84
Step-by-step explanation:
at 45% off the case is $5.41
Therefore this $5.41 is only 100% - 45% = 55% of the original price
x = original price
55% of x = $5.41
55/100 x = 5.41
x = 5.41 * 100 / 55
x = $9.84
