are vertically opposite.
This means that

Similarly
and
are supplementary angles
So:

Make
the subject



The relationship between
and
is that they are supplementary angles because:

Answer: Domain: All real numbers. Range: y=-37
Step-by-step explanation: The function of f(x)=-37 is a horizontal line that goes from negative infinity to positive infinity. The domain can be any number since there is no limit on what the x value can be. The range will always be y=-37 because no matter what x will equal, y will always be equal to -37 in the function of f(x)=-37.
Should be 40ft. If not, I dearly apologize.

The two triangles are isosceles.
Both triangles have the equals sides equal to 6
Both ∠ 1 and the ∠2 are the opposite angles to the different side of their respective triangles.
The opposite side to ∠ 1 is shorter than the opposite side to ∠ 2, which implies that ∠1 is less than ∠2.
Then the inequality that relates those angles is
∠1 < ∠2
