In referencing this: https://nzmaths.co.nz/ao/gm5-5-deduce-angle-properties-intersecting-and-parallel-lines-and-angle-properties-polygons-and-a Vertically opposite angles are equal So you could equate A to B, so just make the expressions equal to each other then solve for X.

Shadow:

\[6x + 18 = x + 93\] Subtract x from both sides \[5x + 18 = 93\] Subtract 18 from both sides \[5x = 75\] Divide both sides by 5 \[x = 15\]

Shadow:

Input x in for either expression then you can solve for the angle value

Shadow:

Remember since <B = <A, it doesn't matter which expression you use. Both will provide the correct answer.
