Question

Accepted Answer

# Explanation:
## Step1: Recall the triangle - angle sum theorem
The sum of the interior angles of a triangle is $180^{\circ}$. Let the unknown angle be $x$. Then $x + 40^{\circ}+70^{\circ}=180^{\circ}$.
## Step2: Solve for $x$
$$
\begin{align*}
x&=180^{\circ}-(40^{\circ} + 70^{\circ})\
x&=180^{\circ}-110^{\circ}\
x& = 70^{\circ}
\end{align*}
$$

# Answer:
$70^{\circ}$
