Question

In the given figure, $A C perpendicular C E$ and $angle A colon angle B colon angle C equals 3 colon 2 colon 1$ , then the value of $angle E C D$ is

$70^{\circ}$
$50^{\circ}$
$60^{\circ}$
$90^{\circ}$ .

The correct answer is: $60 to the power of ring operator end exponent$

In the question we have to find the given angle ECD
$angle A colon angle B colon angle C equals 3 colon 2 colon 1 L e t comma angle A equals 3 x angle B equals 2 x angle C equals x A p p l y i n g space a n g l e space s u m space p r o p e r t y space o f space t h e space t r i a n g l e angle A plus angle B plus angle C equals 180 degree 6 x equals 180 x equals 30 angle A equals 3 x equals 90 degree angle B equals 2 x equals 60 degree angle C equals x equals 30 degree angle C plus angle A C E plus angle E C D equals 180 degree angle E C D equals 180 minus 120 equals 60 degree$

Hence Choice 3 is correct
