When Peter does this, he is creating two sides of a right-angle triangle. The distance from his house to that point will be the hypotenuse of the triangle thus, to work out the length of the hypotenuse, we have to use Pythagoras Theorem! So:
a² + b² = c²
15² + 15² = c²
225 + 225 = c²
450 = c²
15√2 = c
21.21320344 = c
So, this rounded to the nearest tenth would be:
21.2 meters !
First you write down the number of sides that it has.
Let "n" represent the number of sides.
So you have a hexagon which of course is 6 sides.
The next step is to find the SUM of Interior Angles which is (n-2) x 180
So 6 - 2 is 4 and x 180 = 720
The last step is to divide by the original number of sides the polygon has. So since a hexagon has 6 sides, you'd do 720 / 6 =120
Your answer is 120
Answer:
I thinks its r = 11
Step-by-step explanation:
So you just need to take the number to the r and multipliy it by r So,
9x2=18
then minus it by the other number which would Be 7 so.
18-7=11
