Answer:
(328i + 82) / 17
Step-by-step explanation:
`(2i(4+5i)(4-5i))/(4+i)
= (2i(16 - 25i^2)) / (4 + i)
= (2i( 16 + 25) )) / (4 + 1) [Note:- i^2 = -1]
= 82i / (4 + i)
= 82i(4 - i) / (4 + i)(4 - 1)
= 328i + 82 / (16 - i^2)
= (328i + 82) / 17
Answer:
x = 62
Step-by-step explanation:
X and 62 are vertical angles and vertical angles are equal.
x = 62
I/44000=3100/38000
i=3100(44000)/38000
i=$3589.47 (to nearest cent)
