ss7ja [257]

Answer:

x + 5

Step-by-step explanation:

A = LW

W = A/L

W = (x^2 + 16x + 55)/(x + 11)

W = [(x + 11)(x + 5)]/(x + 11)

W = x + 5

ABCDEFGHIJ is a regular decagon with a radius of 25.89 units. Find the area of ABCDEFGHIJ. Round the answer to the nearest tenth

Verdich [7]

Let's call the midpoint of GF M.
MF = 16/2 = 8
KF = 25.89
MK = sqrt(25.89^2 - 8^2)
MK = 24.62
MKF = 8 * 24.62 / 2 = 98.48 square units for one triangle
There are 20 of those triangles that make up the decagon.
Therefore the total area = 20(98.48) = 1969.6 which would be option C

what is the slope of a 5-foot high platform that begins at ground level 10 feet from the base of the platform?

Sladkaya [172]

Answer:

11.2 feet

Step-by-step explanation:

Given: Height of platform (Opposite)= 5 foot

Distance of slope from the base of platform (adjacent)= 10 feet

Picture drawn to show the measurement.

Lets find the length of slope.

Using the Pythagorean theoram.

$hypotenous^{2} = opposite^{2} + adjacent^{2}$

Subtituting the value in the formula.

$hypotenous^{2} = 5^{2} + 10^{2}$

⇒ $hypotenous^{2} = 25 + 100$

⇒ $hypotenous^{2} = 125$

Putting square root on both side

We know, √a²= a

⇒ $hypotenous = \sqrt{125}$

∴ hypotenous= 11.18 $\approx 11.2 \ feet$

Hence, the slope is 11.2 feet
