Some are. Others aren't. In order to focus in on it more clearly,
I'd need to see the list of choices that you're looking at.
The answer depends on what X and Y are.
Yes. If an angle of x degree is obtuse then x > 180 deg Suppose x = 180 + y where y is positive. Then x can be divided into two angles of 90+y/2 degrees each y>0 so 90 + y/2 > 90 and so the two angles are obtuse.
x=y is the identity. It is its own inverse. So the inverse is y=x.
To find the inverse of a statement, you negate both the hypothesis and the conclusion. If the original statement is "If X, then Y," the inverse would be "If not X, then not Y." This structure highlights the opposite conditions of the original statement.
X + Y⁶X + Y * Y * Y * Y * Y * Y
If x y and y z, which statement is true
y -> x

If x = y and y = z then x = z
x=y is the identity. It is its own inverse. So the inverse is y=x.
X + Y⁶X + Y * Y * Y * Y * Y * Y
what is a program x and y
x+y does not equal 10, which can be written x+y ~= 10 or x+y != 10.
x is odd
900 º If the three angles in the triangle are x, y, and z then: x + y + z = 180º The exterior angles are: (360 - x) + (360 - y) + (360 - z) = 360 + 360 + 360 - (x + y + z) = 360 + 360 + 360 - (180) = 900º
If x and y are the two angles, then x + y = 90 and x - y = 18 Adding the two equations together gives 2x = 108 so that x = 54 and then y = x - 18 = 36
