Answer:
Step-by-step explanation:
Plot that point in the x/y coordinate plane to see that it sits in the third quadrant. From the point, draw a line to the origin, constructing a right triangle. The side adjacent to the angle is -2, the side across from the angle is -5, so we need to find the length of the hypotenuse using Pythagorean's Theorem:
and
so

That means that
and

That means that
and

It also means that

Answer: The tax amount will be $1.60
for the first one, use Pythagoras theory to find the answer which is
opposite2+adjacent2=hypotenus2
the 2 behind all of them describe the square of all of them
P=42 m
1/2 of P=21
1/2 of P= l+w
21=13+8
A=13×8
A=104 m^2. As a result, the length is 13 m, and the width is 8 m. Hope it help!
