Answer:
5² - n
Step-by-step explanation:
Five squared = 5²
n = n Subtract n from 5²
Diff. = 5² - n
We indicate "taking the difference" by a "minus" sign, so all the other options are <em>wrong.

Answer:
x = 16.6
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan 71 = x /5.7
5.7 tan 71 = x
x=16.55400
Rounding to the nearest tenth
x = 16.6
16 x 8 = 128 square feet (area of rectangle)
shaded:
8 x 2 = 16
10 x 1 = 10
1/2 (3)(10) = 15
total shaded area: 16+10+15 = 41 square feet
total non-shaded area = 128 - 41 = 87 square feet
answer
area of the shaded region = 41 square feet
area of the non - shaded region = 87 square feet
| shade | | | Each rectangle stands for one third so shade
