Find the length of the leg of the right triangle leave your answer in simplest form?

Answer:

a =12*sqrt(2)

Step-by-step explanation:

3.  The Pythagorean theorem states

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

a^2 +21^2 = 27^2

a^2 +441 =729

Subtract 441 from each side

a^2 +441-441 = 729 -441

a^2 =288

Take the square root of each side

sqrt(a^2) = sqrt(288)

sqrt(xy) = sqrt(x)sqrt(y)

a = sqrt(144)sqrt(2)

a =12*sqrt(2)

Write an equation parallel to y= -5/2x + 9 that passes through the point (-6,7) brainly
frozen [14]

Answer:

Step-by-step explanation:

If two lines are parallel, that means their slopes are equal.

And we also know that the line must pass through (-6,7)

And with our point-slope equation, we get the equation:

y-7 = -\frac{5}{2} (x+6)

y - 7 = -\frac{5}{2} x-15\\y= -\frac{5}{2} x-8<------ Answer

Hope that helps!
