Answer:
f = 2
Step-by-step explanation:
2 +1.25f = 10 -2.75f
Add 2.75f to each side
2 +1.25f+ 2.75f = 10 -2.75f+2.75f
2 +4f = 10
Subtract 2 from each side
2+4f-2 = 10-2
4f = 8
Divide each side by 4
4f/4 = 8/4
f = 2
Answer:
Because the sin function is positive in the first and second quadrants.
Step-by-step explanation:
We are told that sin(A) = 0.422
Thus;
A = sin^(-1) 0.422
A = 25°
Now,this is just for the first quadrant because this angle could very well be in another quadrant.
Usually in four quadrants of an x-y coordinate, the sin function is negative in the third and fourth quadrants because the x- values there are negative and sin is opposite/hypotenuse. That will lead to a negative value of Sin A since hypotenuse is always positive while the x-values in these quadrants are negative.
So, sin function is positive in the first and second quadrant.
In the first quadrant, it's 25°, however in the second quadrant where it is below the x-axis, the angle will now be: 180° - 25° = 155°
The diagonal of a square is given by:
d = root ((L) ^ 2 + (L) ^ 2)
Where,
L = side of the square.
So we have to clear L:
d ^ 2 = (L) ^ 2 + (L) ^ 2
d ^ 2 = 2 (L) ^ 2
(L) ^ 2 = (d ^ 2) / 2
L = root ((d ^ 2) / 2)
Substituting
L = root (((8) ^ 2) / 2) = 5.66 mm
Then, the perimeter of the square is given by:
P = 4L = 4 * (5.66) = 22.64mm
answer
The perimeter of the square is 22.64mm or
