Add all of the numbers together & divide by how many numbers there are.. so the answer would be 8 :)

8, because if you add 7, 8, 8, 8, 8, 7, and 9 together, you get 64.  Then because there are 8 numbers, you divide 8 from 64, and Boom!

Hope this helps!

first, measures the triangle's angles. They are all 60 degrees. Then, measures the sides. Side 1 is 6 cm long. Side 2 is also 6
jenyasd209 [6]

Answer:

The correct answer is 6 cm.

Step-by-step explanation:

The measure of all angles of the triangle is given to be 60 degrees. This invariably means we are talking about an equilateral triangle as all angles of an equilateral triangle are equal.

Also all sides of an equilateral triangle is known to be equal. Therefore the measure of all sides of the concerned triangle are equal.

Given the measure of two length of sides are 6 cm respectively.

Therefore the length of side 3 is 6 cm, equal to the other two sides.

When a fraction is divided by the difference of 1/2 and 1/6 we get 2/3 what is the fraction
QveST [7]
The difference between 1/2 and 1/6 is 2/6. So to write an expression we could do x divided by 2/6=2/3. So instead of a division expression, we could make that into a multiplication problem 2/6 times 2/3=x.  2/6 times 2/3= 4/18 so your answer is 4/18 or 2/9
