Answer:

4.50\ ft

Step-by-step explanation:

see the attached figure to better understand the problem

In the right triangle ABC

cos(A)=\frac{AC}{AB} -----> the cosine is the adjacent side to angle A divided by the hypotenuse

substitute the values and solve for x

cos(68\°)=\frac{x}{12}

x=12*cos(68\°)=4.50\ ft

2 3 − 5 6 ·8<br><br> Simplify.
Helga [31]

Answer:

-1.33 and so on

Step-by-step explanation:

Take each fraction and plug it into a calculator. 2/3 is really 2 divide by 3. Same with the 5 and 6. You should get 0.67 and so on for 2/3 and 0.83 and so on for the 5/6. Subtract as shown in the problem. You should get 0.67-0.83= -0.1666 so on. Multiply by 8 to get -1.33 and so on. The "and so on" means this decimal is repeating. Hope this Helps!
