Question

NEED DONE FAST GIVING 40 POINTS

Answer 1

To solve this problem you must apply the proccedure shown below:

1. The perimeter of a rectangle can be calculated with the following formula:

$Perimeter=2Width+2Length$

2. The width is:

$Tan\alpha=opposite/adjacent\\Tan(72)=12/W\\ W=(12)(Tan(72))\\ W=3.89 in$

3. Now, you must substitute the values into the formula for calculate the perimeter:

$Perimeter=2(3.89in)+2(12in)\\ Perimeter=31.78in$

Therefore, the answer is: $31.78 in$
