Hey guys please help find the area

Area = 498.8 ft^2

Step-by-step explanation:

One of the segments of the kite forms a triangle.

Using a trigonometry ratio to find the base, tan 30 = opposite/ adjacent

Where opposite = 12 feet

Substitute opposite to find adjacent base.

Tan 30 = 12/base

Base = 12/tan 30

Base = 20.78 feet.

Area of a triangle = 1/2bh

Where the b = opposite = 12 feet

h = base = 20.78 feet

Substitute b and h into the formula

Area = 1/2 × 12 × 20.78

Area = 124.71 square feet.

There are 4 triangular shapes in the figure. Multiply the area by 4. That is,

124.71 × 4 = 498.9 square feet.

Therefore, the area of the shape is 498.9 ft^2

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
