1 because 10/9= 1 1/10
which is closer to 1
Answer:
x ∈ {2π/3, π, 4π/3} ≈ {2.09440, 3.14159, 4.18879}
Step-by-step explanation:
The equation can be put into standard form by adding 1:
2cos²(x) +3cos(x) +1 = 0
(2cos(x) +1)(cos(x) +1) = 0
Values of cos(x) that make this true* are ...
cos(x) = -1/2 . . . . . . . . . true for x=2π/3, x=4π/3
cos(x) = -1 . . . . . . . . . . . true for x=π

A graphing calculator can be helpful here, too.
_____
* from your knowledge of the short table of trig functions and their signs in different quadrants
.86486486 percent but round it
Answer:
Alternate Exterior Angles
Step-by-step explanation:
Alternate exterior angles are two angles on the opposite outer sides of two parallel lines cut by a transversal.
The two angles given, 2 and 7, are alternate exterior angles.
Hope it helps! :)
The formula is SA = bh + (s1 + s2 + s3)H
The answer is 420m^2
I hope this helps! :)
