94
(85+89+92+x)/4 = 90
(266+x)/4 = 90
(Multiply by 4 on each side to get rid of it)
266+x=360
(subtract 266 from each side)
x = 94
Answer:
Step-by-step explanation:
If x=2, 2x^3-2x^2+3x-2 ≠ 0, so (x-2) is not a factor.
-2 degrees because 4 times -3 is -12 and 10-12 is -2
Complementary angles add to 90 degrees. This means that 65 + x = 90, so x = 90 - 65 = 25.
