The answer is D. 80°. Angle B is 60 because the angle is adjacent. That makes 60 the vertical angle for the second angle in the triangle with the 40. Since we know two of the angles, we add them together to get 100. 180-100 is 80°

What is the slope of a line that is perpendicular to the line?
jolli1 [7]
The slope is 4.

To find the perpendicular slope, you use the negative reciprocal of the slope you already have. Since the original slope is -1/4, you flip -1/4 to get -4. You then find the negative of -4 to get 4

What is the area of the figure below​
jek_recluse [69]

Answer:

Option A

Step-by-step explanation:

Area of the composite figure = Area of ΔABH + Area of BCGH + Area of ΔDEF

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

                        = \frac{1}{2}(6)(8-5)

                        = 9 in²

Area of the trapezoid = \frac{1}{2}(CG+BH)(\text{Distance between these lines})

                                    = \frac{1}{2}(6+4)(5)

                                    = 25 in²

Area of ΔDEF = \frac{1}{2}(8)(6)

                       = 24 in²

Therefore, area of the given figure = 9 + 25 + 24

                                                          = 58 in²

Option A will be the correct option.
