Answer:
rhombus
Step-by-step explanation:
in square and rectangle there are 90 degrees
and in parallelogram only opposite sides eq.
but in rhombus all sides are eq. and angle can be any
hence ans is rhombus

Answer: y= -2x - 4
Step-by-step explanation:
This is a straight line, so it can be expressed by y = mx + c.
Here c is y-intercept, which means where line cuts the y-axis. We can see from the graph that the line cuts the y-axis at -4.
So, c = -4.
m is slope.
Use slope formula to find m.
m = ( -4 - 0 ) / ( 0 -(-2))
m = -4 / 2
m = -2
Now put values into this equation
y = mx + c
y = -2x - 4
A cube, is made off 6 squarial faces, so all faces on that cube, are squares, the front, back, left, right, top and bottom.
a square has all equal sides, and also all right angles, so all angles in a square are 90°. Let's say the sides are "x" long.
now, if we run a plane on that cube diagonally, check the picture below, the diagonal side at the bottom, by usin the 45-45-90 rule as you see it there, will be x√2.
let's keep in mind that, "x" is opposite side of that angle θ, and then x√2 will be the adjacent side of it.
and we can use those two to get the tangent and then the inverse tangent to get the value, as you see it in the picture.
if you need the angle in radians, run the inverse tangent again, just make sure your calculator is in radians mode.
Next time add an image, but know that the expression is equal to 657 since..
83 * 8 -7
Use PEMDAS
664 - 7
657
You need to multiply the two numbers. Or you can use long addition.
