Answer:
-3
Step-by-step explanation:
means ![3(\cos(180^\circ)+i \sin(180^\circ))](https://tex.z-dn.net/?f=3%28%5Ccos%28180%5E%5Ccirc%29%2Bi%20%5Csin%28180%5E%5Ccirc%29%29)
What is the
-coordinate value that corresponds to
. That value is -1.
What is the
-coordinate value that corresponds to
. That value is 0.
So this implies
.
![3(\cos(180^\circ)+i \sin(180^\circ))](https://tex.z-dn.net/?f=3%28%5Ccos%28180%5E%5Ccirc%29%2Bi%20%5Csin%28180%5E%5Ccirc%29%29)
![3(-1+i (0))](https://tex.z-dn.net/?f=3%28-1%2Bi%20%280%29%29)
![3(-1+0)](https://tex.z-dn.net/?f=3%28-1%2B0%29)
![3(-1)](https://tex.z-dn.net/?f=3%28-1%29)

Answer:
B SSA
Step-by-step explanation:
Geometric proofs can be used to show that the two triangles are congruent using ASA, SAS and SSS.
However, there is no such thing as SSA in geometry because an angle and two sides can not show congruence of triangles. This is so because the angle is not an included angle.

Answer:
C, 39.3 in²
Step-by-step explanation:
Lets first find the area of the rectangle part of the house.
To find the area of a rectangle its base × height.
So its 6×4=24 in².
Now lets find the area of the top triangle.
Area for a triangle is (base × height)/2.
The height is 3 inches, because its 7-4. While the base is 6 inches.
(6×3)/2=9 in².
To find the area of the half circle the formula, (piR²)/2.
The radius of the circle is 2 because its half of the diamter which is 4.
(pi2²)/2=6.283 in².
Now we just need to add up the area of every part,
24+9+6.283=39.283in²
