Matematika Jika vektor ā = 2i - 3jdan b = 5j, maka Panjang vektor (a+b)= .... a. O b. V2 c. 22 d. 4v2 e. 8​

Jika vektor ā = 2i - 3jdan b = 5j, maka Panjang vektor (a+b)= .... a. O b. V2 c. 22 d. 4v2 e. 8​

Jawab:

jawabannya C. 2√2

Penjelasan dengan langkah-langkah:

a + b = ( 2i - 3j) + 5j = 2i + 2j

| a + b | = √ 2² + 2² = √ 4 + 4 = √8 = 2√2
