Answer:

x = 10

Step-by-step explanation:

Use Pythagorean theorem to find the value of x

Focus only on one half of the triangle

if we slice the triangle in half, we get a right angle triangle

the base will now be 12/2 = 6

Pythagorean theorem says that a^2 + b^2 = c^2

plug 6 as a and 8 as b.

this should give you 100

now take the square root to find c (which equals x)

Ta-da!

what is the area of a parallelogram if the coordinates of its vertices are (0,-2) (3,2) (8,2) and (5,-2)?
amm1812

A common strategy when finding the area of a polygon while you're only given the coordinates is to employ the shoelace formula. To start, we have to order the coordinates either clockwise or counterclockwise ( see attatched for a drawing). So, now we can order the coordinates counterclockwise, adding the first entry again at the end (see second attatchment) Now we can use shoelace. When going left to right, we'll multiply the numbers and they will be positive, and we'll make those numbers negative. ( see third attatchment). After we add them up and subtract when necessary, we'll divide the whole thing by 2. Here's the math:

\frac{(0*-2+5*2+8*2+3*-2)-(0*2+2*3+8*-2+5*-2)}{2}=20

How many quarts are in 2 & a half gallons
puteri [66]
Hi there!

Using some simple conversions we can determine how many quarts are in 2 & a half gallons.

1 gallon = 4 quarts.
2 gallons = 8 quarts.

Since we're trying to determine how many quarts are in 2 & a half gallons we can separate our problem into how many quarts are in two gallons and how many are in a half a gallon.

2 gallons = 8 quarts.
.5 gallon = 2 quarts.

After adding this together we come up with the answer that there are 10 quarts in 2 & a half gallons. :)

Novosadov [1.4K]

Step-by-step explanation:

Height of the right circular cone = 18.8 metres

And base is 19.3 metres

Volume of the right circular cylinder is given by,

= πr²h

= 3.14 × (19.3)² × 18.8

= 21999.98(approx.) cubic metre

Rounding off nearest tenth

= 21999 cubic metres
