Answer: The given expression "2 divided by the quantity of 2 plus 5i" can be translated as 2/(2+5i). Simplifying expressions aim is to simplify it into its simplest form. Since i = √-1 substitute it into the expression.
2/(2+5√-1)
then multiply it by 2-5√-1 on the numerator and denominator and we have
[2(2 - 5√-1)] / [4 - 25(1)]
(4-10√-1)/(-21)
9514 1404 393
Answer:
∠Z = 34°
∠T = 56°
Step-by-step explanation:
You can solve for x using the measure of the right angle:
90 = 3x +6
30 = x +2 . . . . . divide by 3
28 = x . . . . . . . . subtract 2
Then the measure of T is ...
∠T = 2x° = 2(28)° = 56°
∠Z is its complement: 90° -56° = 34°
The angle measures are ...
m∠Z = 34°
m∠T = 56°
1. 40
2. 43
its just like subtracting when you add a negative number to a positive one. flip them around! makes it a lot easier.
