**Calculus**

A rectangle has a diagonal of 8cm. The diagonal creates a 60 degrees angle at the base of the rectangle. Write an exact expression for the base and the height of the rectangle. ^^ Dont get how to do that, Ive only drawn a triangular diagram, and im confused about the ...

**One Trigonometry Question Please Help!**

since the diagonal of a square of side s is s√2, a diagonal of length 18 means a side of 18/√2 = 9√2 (D)

**maths**

the diagonal intersects the two given sides at (5/3,-4/3) and (-2/3,7/3) The two given sides intersect at (0,0), so we want the line through (0,0) and the midpoint of the given diagonal: (1/2,1/2) Looks like y=x

**algebra**

The length of the diagonal is sqrt[(x2-x1)^2+(y2-y1)^2] = sqrt [9^2 + 9^2] = 9 sqrt2 Since the diagonal of a square is sqrt2 times longer than a side, the side length must be 9. Now calculate the perimeter.

**solid mensuration**

In a cyclic quadrilateral, the diagonal would be the hypotenuse of two right-angled triangles. Clearly if the hypotenuse , in this case the diagonal, is 4√3, then the two given sides of 4 and 5 cannot be sides of the same triangle. I made the following sketch Quad ABCD ...

**Algebra 2**

1) original volume= s^3 new volume=s^3-169=(s-.5)^3 multipy out the cube, and then solve. The s^3 should go away. 2)in a rectangle, diagonal^2=width^2+length^2 let n be width, n+2 be length, and n+4 be diagonal (n+4)^2=n^2+(n+2)^2 solve for n

**Physics**

The net force is the diagonal that would be formed if you form a rectangle, with the two vectors being two of the adjacent sides. Use the diagonal that starts at the origin. You can get the magnitude of the net force vector from the Pythagorean theorem. F = sqrt[(400)^2 + (500...

**Square roots**

The diagonal of a square has length square root 2 X s, where s is the length of a side of the square. What is the length of the diagonal in a square with sides that are 13 cm? Round your answer to the nearest tenth.

**math**

two 22.5 degree cast iron bend are offset by 3 feet 5 inches, so the diagonal that joins them must have one hub. you need to measure a 10 foot length of 3 inch pipe and cut it for the diagonal. if you measure from the extreme end of the hub, at what dimension will you make ...

**Math!Please Help.!**

Hi.-It's Margie and I have a Math Lab to do but I don't get this.If you can, please help.: Use the Pythagorean Theorem to find the diagonal of the new room. length=22 width=25 area=350 Is the area supposed to be 550 instead of 350? Area of a rectangle is length times width, ...

**geometry**

sheesh! - draw one. There's only one diagonal, making 2 triangles. a quad has only 4 points. pick a vertex. 2 of the other points form the adjoining side, leaving only 1 point left to form a diagonal.
