So,
We see in Statement 3 that WY = WY. This seems obvious, but it ensures that quantities don't change their values. We call this property of something being equal to itself, the "reflexive property."
The correct answer is the third option.
Assuming that x is on the horizontal and y on the vertical y = 35*x so the second option
If angle A measure 90° and angle B is 45° , that leaves 45° for angle C. (90 + 45 + 45 = 180)
If both non right angles are 45° we have an isosceles right triangle and AC is also 19 feet.
So now we can use the Pythagorean theorem to find the missing side.
a² + b² = c² and we are looking for BC - the hypotenuse of the triangle
19² +19² = c² 361+361 = c² 722= c² and c=√722 or about 26.87
It is seventy-eight and six tenths
