Tan = o/a and = 3/4 so the opposite is 3 and the adjacent is 4
Answer:
let required no be x

by doing crisscrossed multiplication

42=7x
dividing both side by 7

6=x
therefore x=6
therefore value of remaining no.is 6
First bring all terms in 'a' to the left side of the formula by subtracting ac from both sides
ab - ac - cd = ac - ac
ab - ac - cd = 0
now add cd to both sides
ab - ac -cd + cd = cd
ab - ac = cd
now factor the left side by taking out the 'a'
a(b-c) = cd
now divide both sides by (b-c)
a = cd / (b-c)
done
