Answer:
17.82
Step-by-step explanation:
since this is a right triangle you can use one of the trigonometric ratios, in this case it would be cosine because you have values for the adjacent and hypotenuse sides
cos(27°) = x/20
x = 20 · cos(27°)
x = 17.82
Following your directions...
50+1(10)-2(10)= 50+10-20=60-20=40
answer: 40
