One side of trapezoid is 10 inches. The side parrellel to this is twice as long as this side. The height is half as long as the
madam [21]
The first side is 10 inches
the side parallel to this is (10×2)= 20 inches
Height is half the length=1/2×20=10 inches
The area of trapezium is given by:
Area=1/2×h×(a+b)
where a and b are the sides, h is the height. Thus the area will be:
Area=1/2×10×(20+10)
=1/2×10×30
=150 sq. inches

Can you double a square with a straightedge and a compass?
sergejj [24]
I'd say yes.  If you use the diagonal as a reference.  Take the square and set your compass to the width of the diameter of the square.  Now put it on the page and mark a point.  Put the point of the compass on that mark and make another mark.  Now you can connect the two marks with the straight edge and you have a line that, if you made a square with sides that long, it'd have 2x the area of the first one.  That's because the diagonal is the square root of 2 larger than one side.  Square the square root of 2 and you've got 2.  You lust need to make a perpendicular line to the first one to get the box going.

Help please I don’t understand this problem
Molodets [167]

Answer:

A

Step-by-step explanation:

We know that identity:

cos^2x+sin^2x=1.

From that we have:

cos^2x=1-sin^2x.

So it is:

cos^2x-sin^x=(1-sin^2x)-sin^2x=1-2sin^2x.

And this is A).

B) is not treu because cos^2 is not sin^2x+1

C) is not true because cos^2x-sin^x=1 is false.

D) is not treu because cos^2x is not sin^2x-1
