Verified answer

x/16 = cos 60°

x

= 16 cos 60°

=16×(1/2)

Answer choice:

A. 8

x = 16 cos(60°) = 16/2 = 8 {A}

cos 60 ° = x / 16

x = 16 cos 60°

x = 8_______option A

x = 16sin(30) = 8

cos60 = x/16

1/2 = x/16

x = 8

cos x = x/16

1/2 = x/16

x = 8

cos(60) = adj/hyp= x/16

1/2 = x/16

cross multiply

2x=16

x=8

degree 30-60-90 edge 1,√3, 2

16/2=8

1*8=8

so the value of x is 8

A. 8
