Find the area of the shaded polygons:
tigry1 [53]

Answer:

10

4

Step-by-step explanation:

Purple: This makes two trapezoids. A=(a+b)/2 times h

1st = (4+1)/2 x 1 = 2.5  

2nd = (4+1)/2 x 3 = 5/2 x 3 = 2.5x3=7.5

Total = 2.5+7.5=10

Green: if you draw a line down the center, you can divide these into two more manageable triangles. A=1/2bh

1st = 1/2x2x2 = 2

2nd = 1/2x2x2 = 2

Total = 2+2=4

Solve using long division.
Mkey [24]

Answer:

Quotient is 3x-5 and remainder is 0.

Step-by-step explanation:

Given:

Dividend = 3x^2+7x-20

Divisor = x+4

The long division is shown in the attachment.

Step 1: we need to divide 3x^2+7x-20 with x+4 we first multiply x+4 with 3x we get the remainder as -5x-20

Quotient as 3x.

Step 2: Now the dividend is -5x-20 and divisor x+4 now we will multiply x+4 with -5 we get the remainder as 0 and Quotient as 3x-5

Hence Quotient is 3x-5 and remainder is 0.

  • [Right Triangles Only] SOHCAHTOA  
  • [Right Triangles Only] sinθ = opposite over hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Identify</u>

Angle θ = A

Opposite Leg = 27

Hypotenuse = 42

<u>Step 2: Solve for </u><em><u>A</u></em>

  1. Substitute [sine]:                                                                                             sinA = 27/42
  2. Simplify:                                                                                                           sinA = 9/14
  3. Trig inverse:                                                                                                    A = sin⁻¹(9/14)
  4. Evaluate:                                                                                                         A = 40.0052°
  5. Round:                                                                                                             A ≈ 40°
