If p∥q, m∠1=5b+23, and m∠11=2b+10, find m∠2, m∠4, m∠10, and m∠12

In the first column of the table, missing number is 49, while in the second column of the table, missing numbers are 48 and 56.

Explanation:

Since, it is the multiplication table, therefore there must be logic of multiplication.

In first column numbers are 35, 42.

And we can write them 7×5, 7×6.

So, the third number should be 7×7.

So the first column should be 7×5, 7×6 7×7 ⇒ 35, 42, 49.

Similarly the second column should be 8×5, 8×6, 8×7⇒40, 48, 56.
