Answer:
2 cis (7/6 pi)
Step-by-step explanation:
r = sqrt( a^2 + b^2)
r = sqrt (-sqrt(3) )^2 + (-1)^2)
= sqrt(3 +1)
= sqrt(4)
= 2
theta = arctan (b/a)
theta = arctan (-1/-sqrt(3))
theta = 30
but this is in the third quardrant -a and -b
so add 180
theta = 210 degrees
convert this to radians
210 * pi/180 = 210/180 * pi = 21/18 * pi = 7/6 * pi
r cis (theta)
2 cis (7/6 pi)
|x+y| = |-8+(-13)| = |-8-13| = |-21| = 21

Step-by-step explanation:
This took me a very long time to complete so your welcome ;)
To find out if the triangle is a right triangle, we must check if the following equation is true:
on the left side, we have:
and on the right side, we have:
since on both sides we get 625, we have that the brace forms a right triangle.
Answer:
The area is 35 inches
Step-by-step explanation:
You will need to cut the shape into 3 parts
the 3 by 3
2 by 5
and 4 by 4
after that you multiply the numbers to get the area of the 3 parts.
The final step is to add them all up
