What is the length of the hypotenuse? If necessary, round to the nearest tenth.

PolarNik [594]

Answer:

hypotenuse = 25 yards

Step-by-step explanation:

Use pythagorean theorem

c^2 = a^2 + b^2 where c = hypotenuse and 'a' and 'b' are the legs

hyp^2 = 24^2 + 7^2

hyp^2 = 625

hyp = 25 yd

PLEASE HELP ME I NEED HELP ASAP!!!! PLEASE HELP ON A AND B

Answer:

Step-by-step explanation:

The opposite sides of the rectangle are of equal length.

Therefore we have the system of equations:

$\left\{\begin{array}{ccc}3y=2+x&\text{subtract 2 from both sides}\\3x=2+x+5y&\text{subtract x from both sides}\end{array}\right\\\\\left\{\begin{array}{ccc}3y-2=x&(*)\\2x=2+5y&(**)\end{array}\right$

Substitute from (*) to (**):

$2(3y-2)=2+5y\qquad\text{use distributive property}\\\\(2)(3y)+(2)(-2)=2+5y\\\\6y-4=2+5y\qquad\text{add 4 to both sides}\\\\6y=6+5y\qquad\text{subtract 5y from both sides}\\\\\boxed{y=6}$
