Answer:

Step-by-step explanation:

set the equation up solving for cosine

cos=adjacent/hypotenuse

cos 70°= 14/x

multiply both sides by x

x (cos 70°)= 14

now to get x by itself divide by cosine 70°

x/cos 70°= 14/ cos 70°

x= 14/ cos 70°

solve for x

x= 14/ .34

x= 41.2

i hope thats right, otherwise it is 22.1
