Length of the chord

Calculate the length of the chord in a circle with a radius of 25 cm with a central angle of 26°.

Correct answer:

x =  21.92 cm

Step-by-step explanation:

r=25 cm α=26  β=2 α=2 26=52   sin β/2 = x/2 : r sin α = x/2 : r  x=2 r sinα=2 r sin26° =2 25 sin26° =2 25 0.438371=21.92=21.92 cm
