Bila terdapat vektor-vektor :
C = 70 satuan, ke Barat
D = 50 satuan, -530 terhadap timur (tanda negatif berarti arahnya searah jarum jam) E = 80 satuan ke utara
F = 30 satuan ke Timur
G = 40 satuan, -370 terhadap barat
R = lambang dari vektor resultan penjumlahan atau pengurangan vektor-vektor

Bila R = D + G maka berapakah R (gunakan metode penguraian) ?

tolong jawab secepatnya besok di kumpulkan !, terimakasih

Following WWI in North America and most of Europe there was a recession that led to economic decline. The recession in the United States did not last long and was followed by nearly a decade of major economic growth that made the United States the most powerful economy in the world.

After WWI, America's economy initially experienced a boom characterized by industrial growth and a rise in consumer spending during the 'Roaring Twenties'. However, challenges such as agricultural struggles and inflation hinted at underlying instabilities, ultimately leading to the stock market crash in 1929. These factors contributed to profound economic changes in the following decade.

Diketahui:Vektor D = 50 satuan, sudut -53 derajat terhadap timurVektor G = 40 satuan, sudut -37 derajat terhadap baratDitanya: R = D + G, berapa besar dan arahnya (pakai metode penguraian)?---Langkah 1: Uraikan vektor DSudut -53 derajat artinya 53 derajat ke bawah dari timur (kuadran IV)Dx = 50 × cos(53) = 50 × 0.6 = 30Dy = 50 × sin(53) = 50 × (-0.8) = -40---Langkah 2: Uraikan vektor GSudut -37 derajat artinya 37 derajat ke bawah dari barat (kuadran III)Gx = 40 × cos(37) = 40 × (-0.8) = -32Gy = 40 × sin(37) = 40 × (-0.6) = -24---Langkah 3: Jumlahkan komponenRx = Dx + Gx = 30 + (-32) = -2Ry = Dy + Gy = -40 + (-24) = -64---Langkah 4: Hitung besar resultan RR = akar dari (Rx² + Ry²)R = √((-2)² + (-64)²)R = √(4 + 4096)R = √4100R ≈ 64.03 satuan---Langkah 5: Tentukan arah vektor RTan θ = |Ry / Rx| = 64 / 2 = 32θ ≈ tan⁻¹(32) ≈ 88.2 derajatKarena Rx negatif dan Ry negatif → Kuadran IIIJadi arah = 180 + 88.2 = 268.2 derajat dari arah timur searah jarum jam---Jawaban akhir:Besar R ≈ 64.03 satuanArah R ≈ 268.2 derajat terhadap timur (searah jarum jam) atau hampir ke arah selatan
