sorry if this and are wrong
We know that
∠ECD=∠ACB------> given in the problem
∠DEC=∠CAB------> 90°
so
∠EDC=∠ABC
therefore
triangles EDC and ABC are similar
<span>So
the ratio of the legs are equal</span>

the answer isAC is equal to 126
There are 12 five minutes in one hour and 1 hour correspond to 360°, then each 5 minutes represents 360/12 = 30°
From 1:20 to 1: 55 we have 35 minutes or 7 x 5 minutes or
7 x 30° = 210°
To convert degree into radian, we apply the following formula:
degree/180° = radian/π
210/180 = r/π or (cross multiplication) →Radian = (π x 210/180
→ Radian = 7π/6 (simplify by 30)
I did this last year it is <span>D.

Answer: yes they probably are because they can be any size
