Answer:
∠ 5 = 49°, ∠ 6 = 131°
Step-by-step explanation:
∠ 5 and 49° are corresponding angles and are congruent, then
∠ 5 = 49°
∠ 5 and ∠ 6 are adjacent angles and are supplementary, sum to 180° , that is
∠ 6 + ∠ 5 = 180°
∠ 6 + 49° = 180° ( subtract 49° from both sides )
∠ 6 = 131°
Answer:
(4x -3yi) (4x+3yi)
Step-by-step explanation:
We have a^2 + b^2
Over the complex number, this is equal to
(a-bi) (a+bi)
(4x -3yi) (4x+3yi)
