Question

10 part a consider the figure below: the two given angles are angles part b find the value of x. x =

Explanation:

Step1: Recall angle - relationship definition

Supplementary angles add up to 180°. Since $\angle AOC$ and $\angle BOC$ form a linear - pair (lie on a straight line), they are supplementary.

Step2: Set up an equation

We know that $x + 70^{\circ}=180^{\circ}$.

Step3: Solve for x

Subtract 70° from both sides of the equation: $x=180^{\circ}-70^{\circ}$.

Answer:

Part A: supplementary
Part B: $x = 110^{\circ}$
