The half of 3/4 is 0.375, or 3/8. All you have to do is multiply 3/4 times 1/2.
A. 2x3=6 and 6x12=72 so 78 is greater than 36
6+72=79 which is less than 90
Measure B is 90 because 17x+=180/2
and x=5
when you plug that into 17x+5 you get 90
Answer:
(-3, 3√3)
Step-by-step explanation:
Evaluate each of the coordinates. Keep or drop the "i" as your convention requires.
6(cos(120°), i·sin(120°)) = (6·cos(120°), i·6·sin(120°)) = (6(-0.5), i·6·√3/2)
= (-3, 3√3 i)
You may want the (x, y) coordinates written as (-3, 3√3).
