Answer:

Step-by-step explanation:
1 Equation is given, so solving for "x" would mean an expression for "x", where
x = SOMETHING
First, we need to isolate x, so we need to take "8y" to the other side, we have:

Now, since we don't have "x" isolated yet, we need to take out the 2, so we will divide both sides by 2 to get x isolated. Shown below:

So, x has this expression 
The answer is TX. The sides of each triangle are correspondent, so RS is congruent to TX.
Just do 3/4 divided by 1/8 - answer should be 6
Answer:
Complementary Angles
Step-by-step explanation:
When all angles are added together they have a sum of 90°. Two angles that have a sum of 90° are complementary angles.
I know this is 90° because it is a right angle.
The formula for the area of a semicircle is equivalent to the area if it were a circle divided by 2. Since the bottom edge of the window is 36 inches long, this means that its diameter is also 36 inches long. This gives an area of 508.94 square inches.
The solution is:
A = Acircle/2 = pi*r^2/2 = pi*(18)^2/2 = 508.94 in^2
