16 teams in a football league, each team plays each other twice , how many games are there in the football league in total ?

120 games.

Step-by-step explanation:

We have been given that there are 16 teams in a football league. Each team plays each other twice. We are asked to find total number of games are there in the football league.

We will use formula to solve our given problem.

Each team will play matches with one team less as it will not play match with itself.

We will divide all number of matches by 2 to avoid repetition.

Therefore, there are 120 games in the football league.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
