a 25 foot ladder is placed 7 feet away from wall

how high up the wall will the ladder reach

A 18

B 20

C 22

D 24

24 feet

Step-by-step explanation:

The ladder and the wall form a right triangle, so we can use Pythagorean Theorem

a^2+b^2=c^2

25 is c, or the hypotenuse, because it is opposite the right angle.

7 is a, and x is b.

7^2+x^2=25^2

Solve the exponents

49+x^2=625

Subtract 49 from both sides

x^2=576

Take the square root of both sides

x=24

The ladder reaches 24 feet up the wall

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
