Answer:

Well, it's Pythagoras Theorem

hyp²= opp² + adj²

hyp (hypotenuse)

opp (opposite)

adj (adjacent)

Since, we already have hypotenuse and opposite

15²= 9² + adj²

making adjacent the subject of formula

15²-9² = adj²

adj² = 225-81

adj² = 144

make adjacent subject formula by removing the ²

so,

[tex]adj = \sqrt{144} [/tex]

adj = 12
