Answer:
41.7m²
Step-by-step explanation:
As we can see, the area of this shape is simply the sum of 3 rectangles
Rectangle A has an area of 6 times 4 or 24m²
Rectangle B has an area of (3.8-2) times 3.5 or 1.8 times 3.5 or 6.3m²
Rectangle C has an area of 3 times 3.8 or 11.4m²
Adding that up gives 41.7m²
Menjawab:
[(√1-p²) -3√p] / 2
Penjelasan langkah demi langkah:
Dari identitas trigonometri, pemuaiannya benar:
Cos (A + B) = cosAcosB-sinAsinB
Menerapkan ini dalam memperluas cos (x + 60).
cos (x + 60) = cosxcos60 - sinxsin60
Jika sinx = p = berlawanan / sisi miring
opp = p, hyp = 1
adj² = 1²-p²
adj = √1-p²
Cos (x) = adj / hyp = √1-p² / 1
Cos (x) = √1-p²
Cos60 = 1/2 dan sin60 = √3 / 2
Mengganti nilai-nilai ini ke dalam rumus
cos (x + 60) = cosxcos60 - sinxsin60
cos (x + 60) = √1-p² (1/2) - p (√3 / 2)
cos (x + 60) = (√1-p²) / 2 - √3p / 2
Temukan KPK tersebut
cos (x + 60) = [(√1-p²) -3√p] / 2
Oleh karena itu cos (x + 60) = [(√1-p²) -3√p] / 2
