If a = 2 + i, and b = 3 – 2i, whats b/a?

1 answer:

3 0

Hello :
b/a = (3-2i)/(2+i)
= (3-2i)(2-i)/(2+i)(2-i)
= (3-2i)(2-i)/(2²-i²) .......i² = -1
= (6-3i-4i -2)/5
=(4 -7i)/5
b/a = (4/5)-(7/5) i

Answer:

<BOD = 120°

<EOC = 200°

<AOC = 135°

Step-by-step explanation:

Given:

<DOE = 115 °

<AOB = 60 °

<BOC = 75 °

<AOB + <BOD = 180°

<BOD = 180° - <AOB = 180° - 60° = 120°

<EOC = <EOA + <AOB + <BOC

As you know <EOA + <DOE = 180°

<EOA = 180° - <DOE = 180° - 115° = 65°

Now you find

<EOC = <AOE + <AOB + <BOC

<EOC = 65° + 60° + 75° = 200°

and

<AOC = <AOB + <BOC = 60° + 75° = 135°
