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 !

Answer:
Step-by-step explanation:
If we have a pizza that has 
slices and we want to split it between 4 friends, then each friend will get 
slices.
Now, Harris is one of those friends so he receives slices, but he eats one less than he receives. Therefore, we subtract one from this expression to get our final answer of .
Hope this helped!
Answer:
Step-by-step explanation:
Longer side =18
side opposite to 30=18/2=9
third side=√(18²-9²)=9√3
380*10⁹=3.8*10²*10⁹=3.8*10¹¹
