Step-by-step explanation:the perimeter is found by L+W+L+W. Each L is going to be the same length and each width is going to be the same length since its a rectangle.
Double the length. 8.3+8.3= 16.6
Then subtract that from the perimeter. 22.4-16.6= 5.8
Then divide 5.8 as that is the total of the two missing sides. 5.8/2= 2.9
A)2.8 b1) 4.5/2.8 b2)impossible because if you want to do trigonometry you can't have that is an angle (Which is 148.1) larger than 90 degrees. but if its angle BAF then the angle would be 2.8/5.3 c)41.32
