It’s a right angle! which equals to 90° you already have 20° and 8° so you add them together and you get 28. now you have to subtract 90-28 which equals to 62.

Brums [2.3K]

Answer:

  • y = 2x + 3
  • y = -6x
  • y = -x + 2
  • y = 2x - 7

Step-by-step explanation:

<u>Slope-intercept form:</u>

  • y = mx + b

<em>Hint. if we have x = 0, then the y-coordinate is the same as b</em>

<u>Slope</u>

  • m = (y2 - y1)/(x2-x1)

33.

  • m = (9 -(-3))/(3 - (-3)) = 12/6 = 2
  • b = 3 as per table (0, 3)
  • y = 2x + 3

34.

  • m = (0-12)/(0 - (-2)) = -12/2 = -6
  • b = 0, as per table (0, 0)
  • y = -6x

35.

  • m = (2 - (-2))/(0 - 4) = 4/-4 = -1
  • b = 2, as per table (0, 2)
  • y = -x + 2

36.

  • m = (-5 - (-1))/ (1 -3) = -4/-2 = 2

Using point (3, -1)

  • -1 = 2*3 + b
  • b= -1 - 6= - 7
  • y = 2x - 7

When using the given diagram to determine the area of the pentagon by decomposition, which statements are correct?:
pogonyaev

Answer:

Options (B) and (E)

Step-by-step explanation:

Area of ΔABC = \frac{1}{2}(\text{Base})(\text{Height})

                        = \frac{1}{2}(14)(6)

                        = 42 in²

Area of trapezoid ADEC = \frac{1}{2}(b_1+b_2)h

[Here, b_1 and b_2 are the parallel sides and 'h' is the height of the isosceles trapezoid given]

= \frac{1}{2}(10+14)(8)

= 96 in²

Area of the pentagon = Area of triangle ABC + Area of trapezoid ADEC

                                    = 42 + 96

                                    = 138 in²

Therefore, Options (B) and (E) are the correct options.
