So hmm check the picture below
a circle has a total of 360°, thus arcBC + x + arcCD is 360, so arcCD is just 360 - 112 - x, whatever "x" was that you found
Answer:
1st answer
Step-by-step explanation:
From pythagorus theorem.
Since hypotenuse

As your question is stated, there is no answer!
I'm going to assume the polynomial you meant is:

To create a perfect square trinomial, take half the coefficient of x and then square it.

In all problems like this, you want to square half the coefficient of x -- always half.
Answer: x=11
Step-by-step explanation:
First distribute 3 to both x and -3.
3x-9=24
Then add 9 to both sides to leave the x on its own.
3x=33
Divide by 3 on both sides.
X=11
Step-by-step explanation:
Area=Length×width
=6 5/7×7 3/5
change the improper fraction to proper
=47/7 ×38/5
=1786/35
=51.03ft²
