Think of the right triangle formed by the ladder, the height of the upper end of the ladder and the distance of the bottom of the ladder from the wall.

Then x = 6 ft and the hyp is 10 ft.  The trig function cos theta  equals "adj side" / hyp, so, in this case,

cos theta = 6/10 = 0.6.  Use the arccos x function on your calculator to find the angle x:

x = 0.927 (radians) = 53.1 degrees.

svlad2 [7]

Answer:

The answer to your question is:

Step-by-step explanation:

12.-

                x² - 6x = 5

                x² - 6x + (3)² = 5 + (3)²

               x² - 6x + 9 = 5 + 9

               (x - 3)² = 14

13.-           x² - 6x = 12

               x² - 6x + (3)² = 12 + (3)²

               x² - 6x + 9 = 12 + 9

              (x - 3)² = 21

              x - 3 = ±√21

             x1 = √21 + 3                     x2 = -√21 + 3

               x1 = 7.58                           x2 = -1.58

14.-           2x² - 24x = - 20            Divide by 2

                x² - 12 x = -10

               x² - 12x + (6)² = - 10 + (6)²

               x² - 12x + 36 = - 10 + 36

              ( x - 6) ² = 26

               x - 6 = ±√26

x1 = √26 + 6                                 x2 = -√26 + 6

x1 = 11.1                                          x2 = 0.9

Find the zero(s) of each function algebraically.<br>f(x) = 8x-16<br>​
vodomira [7]

the zero(s) of function  f(x)=8x-16 is x=2

Step-by-step explanation:

We need to find the zero(s) of function algebraically.

We are given: f(x)=8x-16

To find the zeros we put the function equal to zero.

8x-16=0\\Solving:\\8x=16\\x=\frac{16}{8}\\x=2

So, the zero(s) of function  f(x)=8x-16 is x=2
