Corresponding 82704

On the circular face of the clock, we connect the points corresponding to the numbers 2, 5, and 9 to each other, which creates a triangle. Calculate the sizes of all interior angles.

Correct answer:

α =  45 °
β =  60 °
γ =  75 °

Step-by-step explanation:

φ=360/12=30  t1=2 t2=5 t3=9  A=(t2t1) φ=(52) 30=90  B=(t3t2) φ=(95) 30=120  C=360AB=36090120=150   α=A/2=90/2=45
β=B/2=120/2=60
γ=C/2=150/2=75
