If tay (A+B) = 1 and tan (A-B) = 1/root3
0°<A +B< 90, A >B, then find the values of A and B.​

  2. Answer:

    CORRECT ANSWER 3 ROOT 3 cm.

    HOPE THIS ANSWER MAY HELP YOU TO UNDERSTAND

    IF YOU LIKE THE ANSWER PLEASE MAKE ME BRAINEST AND FOLLOW ME ✨✨✨✨

    Step-by-step explanation:

    Let PA and PB be the two tangents to a circle with centre O and radius 3

    ∴∠APO=∠BPO

    =21×∠APB

    =21×600

    =300

    Also, OA⊥AP and OB⊥BP

    In a right angled triangle OAP,

    tan300=PA3

    ⇒31=PA3

    ⇒PA=33cm

    ⇒PA=PB=3 ROOT 3 cm
