\begin{array}{llll}
origin\\symmetry
\end{array}

so, recall, the function has symmetry when the yielded resulting function resembles the original function, after negativizing the variable(s).

Also recall that minus*plus is minus, and minus*minus is plus.

What is the measure of ∡U in the figure shown? ∘
Blababa [14]

Answer:

∠ U = 70°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

120° is an exterior angle of the circle , then

∠ U + 50° = 120° ( subtract 50° from both sides )

∠ U = 70°
