Answer:

h = 18( I might be wrong though)

Step-by-step explanation:

If BE and ED are perpendicular, that means this angle is supplementary.

BEF = 3h-12

FED = 2h - 23

BEF + FED = 90

3h-12 + 2h - 23 = 90

5h - 35 = 90

5h = 90

h = 18 degrees

HELP i need the answers to these! explain if possible:)

IrinaVladis [17]

so one: the middle Angles are all 90 degrees triangles equal 180, the angle opposite of "x" is equal to 34 so 180-90-34=x

two: both angles are equal set it up like an equation and solve for n

three: the corner angle of the right triangle is equal to 61 as well again do 180-(61×2)=x

4: do this equation (<ktu)2+ x = 180 then solve for x

5: not exactly.sure what its asking

hope this helps

Find the distance between (2, -75) and (10,235).

zmey [24]

Answer:

310.1

Step-by-step explanation:

Use the distance formula:

$\sqrt{(10-2)^2+(235-(-75))^2}$

Simplify inside the parentheses

$\sqrt{(8)^2+(310)^2}$

Simplify exponents

$\sqrt{64+96,100}$

Simplify by adding

$\sqrt{96,164}$

Simplify

$\sqrt{96,164} =310.1$

Done. B-)

You need to arrange 10 of your favorite books on a small shelf. How many different ways can you arrange the books, assyming that

tensa zangetsu [6.8K]

Answer:

You can arrange the books 3,628,800 different ways.

Step-by-step explanation:

You can imagine that the shelf has 10 "slots" where you can place a book. Each slot can take 1 of the 10 books. However, after you have placed 1 book, there are only 9 possible books to place. After 2 have been placed, there are only 8 possible.

Going left-to-right, the first slot has 10 available books.

Total combinations: 10

The 2nd slot has 9 available books.

Total combinations: 10 * 9

The 3rd slot has 8 available books.

Total combinations: 10 * 9 * 8

This continues for all 10 slots.

Eventually, for slot 10, there is only 1 book possible.

Total combinations: 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1

Multiply all numbers between 10 and 1 with each other is also known as "10 factorial" or "10!"

Thus, the total number of combinations is:

$10! = 10*9*8*7*6*5*4*3*2*1 = 3628800$

Answer: You can arrange the books 3,628,800 different ways.
