in a circle of radius 6cm , a chord is drawn 3cm from the circle (a)calculate the angle subtended by the chord at the centre of the circle
Pls i need a clear and precise solution
so your chord is also 3 cm from the centre.
construct the right-angles triangle
look at the angle it makes at the centre,
cosØ = 3/6 = 1/2
Ø = 60°
the chord subtends an angle of 120°
A clear answer plss
I need a clear answer
Please elaborate how cos∅=0.5,∅=60 and the angle subtends 120
degree
I need a clear understanding
I need a clear understanding
Clear answer please
Please I need the solving with the formula
Cos¢=3/6=1/2
=60°
=120°
