HI PLEASE HELP PLEASE PLEASEE HELP

Answer 1

Explanation:

`26) tan \ 56 =(opposite \ side )/(adjacent \ side)\\\\\\ 1.4826 = (BC)/(12)\\\\\\1.4826*12 = BC`

BC = 17.8 cm

`27) Cos \ x =(adjacent \ side)/(hypotenuse)\\\\Cos \ x = (15)/(18)\\\\\\Cos \ x = 0.83\\\\x = Cos^(-1) \ (0.83)\\\\`

x = 33.9°
