Can somebody give me a detailed equation for this angle, I already have some but i need more thank you.

47 + 2x - 3 = 90

OR

2x - 3 + 47 = 90 (same equation but order of angles reversed)

x = 23

Step-by-step explanation:

47 + 2x - 3 = 90

44 + 2x = 90

(44 - 44) + 2x = 90 - 44

2x = 46

2x/2 = 46/2

x = 23

correct answer:

i^31 = -i

the one that has a slope of 1/2 and is positive.
