The correct answer is
$110^\circ$

Supplement Definition

Two angles are considered supplementary if their sum equals $180^\circ$. To find the supplement of a given angle, you subtract that angle from $180^\circ$.

Supplement Calculation

The question asks for the supplement of $70^\circ$. Let the supplementary angle be represented by '$x$'.

  • Set up the equation based on the definition: $x + 70^\circ = 180^\circ$
  • Solve for '$x$' by subtracting $70^\circ$ from both sides: $x = 180^\circ - 70^\circ$
  • Perform the subtraction: $x = 110^\circ$

Therefore, the supplement of $70^\circ$ is $110^\circ$. This matches Option D.
