The one that is on the top right is the one which is not a linear function
<h3>
Answer: B) 10.3</h3>
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(20) = x/11
11*cos(20) = x
x = 11*cos(20)
x = 10.336618828645
x = 10.3
Make sure your calculator is in degree mode.
6.3=6 and 7.2=7 so 6 x 7 = 42
42 is the answer
If they are similar they are by a ration of 1:2 but you dont know all the angles or all the sides.
