Answer:
-2
Step-by-step explanation:
sec 180 + sin 270 - tan 180 + cot 270
= -1 + (-1) - 0 + 0
= -1 + (-1)
= -2
The values of tan x is undefined for odd number multiples of x.
Thus, the values of tan x is undefined for x = . . . -3(90), -1(90), 1(90), 3(90), . . .
Therefore, the values of x for which tan (x) is undefined are <span>-270°, -90°, 90°, and 270°</span> [option A].
X=2 because -2x+2 Is canceled then add 2x to 6x which is 8x then add 11 to -11 that’s canceled then add 11 to 5 which is 16 then divide 16 by 8x and x =2
