Answer:
To find the answer consider that this is a right triangle and we can use the tangent function in order to find the value of x
remember the acronym soh cah toa.
to use the tangent function we divide the opposite and adjacent side that is what the oa stands for in toa
setting it up looks like this
tan 72° = 
solving for x gives us x= 8×tan 72°
which is about 24.62
Step-by-step explanation:
Area of Frame and Picture
Area = L * W
L = 9
W = 6
Area = 9*6 = 54 in²
Area of Picture
Area = L*W
L = 6
W = 4
Area = 6 * 4
Area = 24 in²
Area of Frame
Area of Frame = Total Area - Picture Area
Area of Frame = 54 - 24
Area of Frame = 30 in²
In order to write an equation you need to find the y-intercept. the way you do this is by plugging in the value 2 and the point into y=mx+b and solving for b. once you plug everything in you get 5=2(1)+b. solving from here you get b=3. putting everything together you get y=2x+3
♥ To solve this you are going to find x. ♥
♥ X in this case is representing a unknown variable, meaning we are not sure of the number x, and to finish the solution to your problem we have to find x.
♥ So to find x the first step is to simplify both sides of the equation.
♥ Starting with distribution:
♥ Now we want to flip the equation.
♥ Our next and almost final step, is to add the number -3 to both sides of our problem. This is going to help us tremendously.
♥ Now our last step before we get our answer is to divide both sides of the problem. In this case we are going to do this:
♥ And then because of that we get our final answer of: -4.

Answer:
The required equation in standard form is 
Step-by-step explanation:
The equation of a circle with center (h,k) an radius, r units is given by the formula;
The given circle has center (-2,0) and radius squared can be calculated from the given area, which is 
We substitute these values into the formula to obtain;
We simplify to get;
