Answer:

<h2>Yes. It's a right triangle.</h2>

Step-by-step explanation:

If a ≤ b < c are the length of the sides of a right triangle, then

a² + b² = c².

We have:

a =30 ft, b = 40 ft and c = 50 ft.

Check the equality:

L = 30² + 40² = 900 + 1600 = 2500

R = 50² = 2500

L = R

The width of a rectangle is 4n-8.5 feet and the length is 8.5n+9 feet. Find the perimeter of the rectangle
Eva8 [605]

Answer: P = 25n + 35

Step-by-step explanation:

The perimeter of a rectangle is twice the sum of length and width.

P = 2(l +w)

P = 2((8.5n+9) + (4n +8.5))

P = 2(12.5n +17.5)

P = 25n + 35

Find the value of sin( \frac{5 \pi }{3} )

Rewrite as sin( \frac{6 \pi - \pi }{3} )

sin( \frac{6}{3} \pi -  \frac{ \pi }{3}  )

sin(2 \pi - \frac{ \pi }{3} )

since sin(π/3) = √3/2

and sin(π-α) = -sinα

α is sin(π/3) of course

-sin( \frac{ \pi }{3} )

- \frac{ \sqrt{3} }{2}
