Answer && Step-by-step explanation:

We know that area for rectangle/square is Width * Height

Triangles 1/2 * Base*Height

we can see the height of the triangle will be 6 feet, as 10 feet is the "height" (length) of the rectangle

solve by multiplying the rectangle's sides (I cant see if that is a 9 or not but:)

9*10 = 90

keep it in mind, now we know 9==base for triangle, thus;

(9*6)*1/2==27

90+27

117 sq ft.

Answer:

A. 117 sq. ft.

Step-by-step explanation:

So first you can multiply the 9x10 because the area of a rectangle is length x width. That gives you 90. The area of a triangle is base x height so it would be 6x9=54 and divide that by 2 which is 27. Then add 27 and 90 snd you get the answer: 117 sq. ft.

Can anyone figure this out for me please? It would be greatly appreciated.

Check the picture below.

now, to get how much is the area of the tiled section, we simply get the area of the whole pool, 53x26, which includes the tiles, and then subtract the area without the tile, the rectangle in the middle, and what's leftover, is the area of the tiled area.

$\bf 53-4\frac{1}{2}-4\frac{1}{2}\implies 53-9\implies \boxed{42}
\\\\\\
26-4\frac{1}{2}-4\frac{1}{2}\implies 26-9\implies \boxed{17}
\\\\\\
\textit{so the area of the rectangle in the middle is}\implies 42\cdot 17\implies 714
\\\\\\
\textit{and the area of the whole pool is}\implies 53\cdot 26\implies 1378$

$\bf \stackrel{\textit{area of the whole pool}}{1378}~~-~~\stackrel{\textit{area of the middle rectangle}}{714}\implies \stackrel{\textit{area of the tiles}}{664}\\\\
-------------------------------\\\\
\textit{we know that is }\$5\frac{1}{2}\textit{ for a foot of tile, then}\stackrel{\textit{price of the tiles}}{664\cdot 5\frac{1}{2}}\implies 3652$

How do I solve 2cos(x)=2sin(2x)

Vedmedyk [2.9K]

2cosx=2sin2x. Sin2x is an identity for 2sinxcos. So 2[2sinxcosx] gives you 4sinxcosx. 2cosx=4sinxcosx. Divide 2cosx on both sides and gives you 2sinx=0 and divide again, sinx=0. Sinx is 0 at 0 and 360 degrees, or pi and 2pi. So thats what x would be. 0,360,pi,2pi.
