Two angles are considered supplementary if their sum equals $180^\circ$. To find the supplement of a given angle, you subtract that angle from $180^\circ$.
The question asks for the supplement of $70^\circ$. Let the supplementary angle be represented by '$x$'.
Therefore, the supplement of $70^\circ$ is $110^\circ$. This matches Option D.
What is the sum of the angle complementary to $15^\circ$ and the angle supplementary to $125^\circ$?

In the given figure, the three parallel lines are cut through by a transversal. Of the marked angles, the greater two are of equal measure. The ratio of a greater angle to the smaller angle is 7 : 3. What is the measure of the greater angle?
There are three points P, Q and R on a straight line such that PQ : QR = 3 : 5. If n is the number of possible values of PQ : PR, then what is n equal to ?
Two cars start from a point at the same time and travel on two different roads at right angles to each other. Their speed is 18 km/h and 72 km/h respectively. What will be the distance between them after 6 seconds?
Express 65° in radian :
The measure of an angle for which the measure of the supplement is four times the measure of the complement is:
AB||CD and EF is the transversal meeting AB and CD at P and Q, respectively. If ∠APE = 6x and ∠PQD = 4x, then ∠APQ =______.
