The angle measure (120°) is the average of the measures of the two arcs (x, 2x). Hence
.. (x +2x)/2 = 120°
.. 3x = 240°
.. x = 80°
The shortest horizontal shift of a sine curve that will turn it into a cosine curve is a shift of <u>90°( π/2 radians)</u>.
The function y = sin x defines a sine wave as a geometric waveform that oscillates (moves up, down, or side to side) frequently. It is an s-shaped, smooth wave that oscillates above and below zero, to put it another way.
Technical analysis and trading both employ sine waves to assist spot oscillator-related patterns and cross-overs.
Similar to the sine graph, the cosine graph is an up-down graph. The sine graph and cos graph are identical except that the sine graph begins at 0, whereas the cos graph begins at <u>90° (or π/2)</u>. The cosine (cos) graph shown below starts at 1 and drops to -1 before rising once again.
Thus, the shortest horizontal shift of a sine curve that will turn it into a cosine curve is a shift of <u>90°( or π/2 radians)</u>.

Answer:
1.5kg = £2.13
Step-by-step explanation:
1kg = $1.42
1000gm = $1.42
0.5kg = $0.71
500gm = $0.71
1. 42+ 0.71 = £2.13 = 1.5kg = 1500gm
Answer:
Perpendicular lines form 90 degree angles. It creates 4 of them, to be exact. Hope this helps! :)
13 I think because they give everyone the same amount
