Answer:

The radius is r=5\ cm

Step-by-step explanation:

we know that

The inscribed angle is half that of the arc it comprises.

so

m

m

substitute

90\°=(1/2)[arc\ AB]

arc\ AB=180\°

That means----> The length side AB of the inscribed triangle is a diameter of the circle

Applying Pythagoras Theorem

Calculate the length side AB

AB^{2}=AC^{2}+BC^{2}

AB^{2}=8^{2}+6^{2}

AB^{2}=100

AB=10\ cm -----> is the diameter

Find the radius

r=10/2=5\ cm -----> the radius is half the diameter

Factoring when a=1 with and without a GCF<br> What is x2+4x-117
quester [9]

Step 1: Make sure that the trinomial is written in the correct order; the trinomial must be written in descending order from highest power to lowest power.

Step 2 : Decide if the three terms have anything in common, called the greatest common factor or GCF. If so, factor out the GCF. Do not forget to include the GCF as part of your final answer.

Step 3 : Multiply the leading coefficient and the constant, that is multiply the first and last numbers together.

Step 4 : List all of the factors from Step 3 and decide which combination of numbers will combine to get the number next to x.

Step 5 : After choosing the correct pair of numbers, you must give each number a sign so that when they are combined they will equal the number next to x and also multiply to equal the number found in Step 3.

Step 6 : Rewrite the original problem with four terms by splitting the middle term into the two numbers chosen in step 5.

Step 7 : Now that the problem is written with four terms, you can factor by grouping.
