Subtract (x+109) from 180; the result is 71-x.  The reason for doing this is that we want to equate "corresponding angles."  71-x and x+89 are corresponding angles.  Set them = to one another and then solve the resulting equation for x:

71-x = x+89
-18 = 2x, so x = -9

Now let's determine the angle x+89.  Since x=-9, that angle is 80 (degrees).

So those to angles added together equals 180° thus all you have to add those together and set it equal to 180 to find hat x equals, and then add 89 to it to find the highlighted angle.

x+109+x+89=180

add the numbers and x's together

2x+198=180

subtract 198 from each side

2x = -18

divide each side by 2

x = -9

Put -9 in for x in the equation x+89 to find that angle

-9+89

=80

ANSWER:

That angle equals 80°

the sum of two numbers is 63. The smaller number is 9 less than the larger number.what are the numbers
dezoksy [38]

Answer:

27 and 36

Step-by-step explanation:

x + (x - 9) = 63

2x - 9 = 63

add 9 to both sides

2x = 72

Divide both sides by2

x = 36

x - 9 = 36 - 9

x - 9 = 27

PLEASE ANSWER THIS AND SHOW WORK. FIND THE SURFACE AREA FOR THE FIGURE BELOW
Varvara68 [4.7K]

Answer:

Total surface area of the given figure is 246.75 square mile.

Step-by-step explanation:

Surface Area of the given figure = Lateral surface area + Area of the base

Lateral surface area of the figure = Sum of the areas of 5 triangular surfaces

                                                        = 5(\frac{1}{2} )(\text{Base})(\text{Slant height})

                                                        = \frac{5}{2}(7)(9.3)

                                                        = 162.75 mi²

Surface area of the pentagonal base = 84 mi²

Total surface area of the figure = 162.75 + 84

                                                    = 246.75 mi²

Therefore, total surface area of the given figure is 246.75 square mile.
