The length the hypotenuse of an isosceles right triangle, or a 45-45-90 triangle, is always radical two times as long as any leg of the triangle. With this, we can set up an equation where x represents the length of a leg.
x
= 8
divide both sides by
x = 8
The length of a leg of the triangle is 8
Since its a right triangle, you can use a² + b² = c²
one of the legs is a and the other leg is b it doesn't matter which one because its addition and works the same way c needs to be the hypotenuse
so its a² + 48² = 50²
a² + 2304 = 2500
- 2304 -2304
a² = 196
√a² = √196
a = 14
There would be 49 gifts on display because 1+3+5+7+9+11+13=49
A’ should be (-5,2) you move over 5 to the left then up three you don’t even have to do any other work negative move to the left or down pos right or up
