 The last choice is correct

Step-by-step explanation: The information given in the diagram: AB is the hypotenuse of a right triangle, and the side opposite the 60° angle is 9 feet. you can use sine = 0pposite/Hypotenuse

You can find the sine of 60° which is the value of the ratio of the opposite side to the (unknown) hypotenuse.  sin 60° = 0.866

You can set up the equation on a scientific calculator as  but to see the logic use the value   0.866 = 9/h

reorganize to solve for h: divide both sides by 0.866 and multiply both by h to get  

h = 9/0.866   solving that you get the length of AB

h = 10.393, which, rounded, is a logical length for the brace on the gate:

 10.4 feet

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

x=5

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.
