Answer:
look below
Step-by-step explanation:
x - 5 = 7
x = 12
.................
x - 8 = 20
x = 28
.................
x + 2 = -1
x = -3
................
x - 9 = 12
x = 21
...............
x + -6 = -7
x = -1
.................
x - 8 = -3
x = 5
..................
-7 - x = -9
-7 = x - 9
2 = x
Hi!
5438724022+100000000=5,538,724,022
The answer is 5,538,724,022
Hope this helps! :)
1 / cos^2 O - 3 / cos O - 2 = 0
1 - 3 cos O - 2 cos^2 O = 0
2 cos^2 O + 3 cos O - 1 = 0
cos O = 0.2807 , -1.78 ( -1.78 cannot be a solution)
O = 74 degrees (from 0.2807) another solution is 360-74 = 286 degrees
Its D
