Answer:
THE CORRECT ANSWER IS 9m.
Step-by-step explanation:
THE LADDER AND THE WALL MAKES A RIGHT ANGLED TRIANGLE IN WHICH THE HYPOTENEOUS IS 15m AND ONE SIDE IS 12m.
AS WE ALL KNOW THAT IN RIGHT ANGLE TRIANGLE HYPOTENEOUS^2=SUM OF SIDE OF SQUARE OF OTHER TWO SIDES.
THEREFORE THE BASE ANGLE=HYPOTENEOUS^2-ONE SIDES SQUARE
A/Q,
(15)^2-(12)^2
225-144=81
THE SQUARE ROOT OF 81 IS EQUAL TO 9.
