Answer:
2 sqrt(3) -2i
Step-by-step explanation:
If we have the magnitude and the theta
z = |z| cos theta + i |z| sin theta
= 4 cos 330 + i 4 sin 330
=4 (sqrt(3)/2) + 4i (-1/2)
= 2 sqrt(3) -2i
Answer:
Step-by-step explanation:
Area of polygon = area of square + area of triangle
Square:
Side = 12 cm
Area of square = side *side
= 12 * 12
= 144 sq.cm
Triangle:
base (b) = 12 cm
Height h = 19 cm
= 6 * 19
= 114 sq.cm
Area of polygon = 144 + 114 = 258 square cm
Answer:
The value of the trigonometric-ratio:
Step-by-step explanation:
Given the angle X
It is clear that:
- The opposite of the angle X = 48
- The adjacent to the angle X = 14
We know that the trigonometric-ratio of Tan X is defined as
Tan X = Opposite / Adjacent
substituting Opposite = 48, and Adjacent = 14
Tan X = 48/14
Tan X = 24 / 7
Therefore, the value of the trigonometric-ratio:
