Question

KnowledgeBoat · Accepted Answer

Since ΔPQR is a right angled triangle, using pythagoras theorem, ⇒ Hypotenuse2 = Base2 + Height2 ⇒ PQ2 = QR2 + PR2 ⇒ 132 = PR2 + 122 ⇒ 169 = PR2 + 144 ⇒ PR2 = 169 - 144 ⇒ PR2 = 25 ⇒ PR = ⇒ PR = 5 cm. By formula, tan A = From figure, Hence, option 1 is the correct option.
