Clock hands

Calculate the internal angles of a triangle whose vertices lie on the clock's 2, 6 and 11 hours.

Correct answer:

A =  75 °
B =  60 °
C =  45 °

Step-by-step explanation:

φ=360/12=30 ° α=(62) φ=(62) 30=120 ° β=(116) φ=(116) 30=150 ° γ=(2+1211) φ=(2+1211) 30=90 °  A=β/2=150/2=75°
B=α/2=120/2=60°
C=γ/2=90/2=45°
