Area = Bh, so 3 * (2/3) = 1
The area of each triangle, since there are two, would be half of the total area, so 1/2
Answer:
8(cos(π) +i·sin(π))
Step-by-step explanation:
The number in parentheses has a magnitude of ...
√(1^2 +(√3)^2) = √4 = 2
Then the cube of that number will have a magnitude of 8, eliminating the 2nd and 4th choices
The angle of the number in parentheses is ...
arctan(-√3/1) = -π/3
Then 3 times that angle will be -π, also π.
The number of interest has a magnitude of 8 and an angle of π, so is written in the desired form as ...
8(cos(π) +i·sin(π)) . . . . . matches the 3rd choice
Answer:
8 units ^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the length of the base and h is the height
b = LK = 4 units
h = J to where LK would be extended to, which would be 4 units
A = 1/2 (4) * 4
A = 8 units ^2
Yea they are cuz they have the same side and angle measurements
