Answer: 0.62
Step-by-step explanation: I got the answer
If you're saying that the scale is 10 cm: 1 mm then the scale will be larger than the actual object because for every 1 mm of the object it will equal 10 cm of the scale drawing.
Nina is 64. I hope this is correct , let me know if it isn’t .
<span>ok
first things first. In all parallelograms, you now that opposite angles
are numerically equal to each other and that the sum off all four
angles must add up to 360.
Therefore based off the picture, angles B and D are equal to each other, and A and C are equal to each other.
(2x-10) = (y+20) B = D
y=2x-30
Now B = 2x -10 and D = 2x-30+20 = 2x-10
Now A = C
Since A = 2x+ 10, we can assume C = 2x + 10
Now we need to find the value of x
so our angle A, B, C, and D add up to 360 so the "master equation" is:
(2x - 10) + (2x - 30 + 20) + (2x + 10) + (2x + 10) = 360
2(2x -10) + 2(2x + 10) = 360
4x - 20 + 4x + 20 = 360
8x = 360
x = 45
Now that we know what x is, we can go back to the angles B and D
remember B = 2x - 10 and D = y + 20
and earlier we stated that y=2x-30
therefore y = 2(45) - 30
Y = 60
Now if you wanted to double check, all you have to do is plug in the x
and y values into the equations and add up all the angles together and
they should add up to 360.
I know I kinda went into too many details, but I'd rather explain it
into too much detail rather than too few details and shortcuts that you
wouldn't be able to follow and understand.
I hope this was helpful =D </span>
