Answer:
He's right it's 0.8 I got the answer right thanks a lot dude
Hey,
So we have to solve this in multiple steps. Step 1 is to find the circumference of the semi-circle and multiply by three since there are three. Step 2 would be to find the perimeter of the rectangle. Step 3 would be to add those two together.
Step 1: To find the circumference of the semicircle use the formula pi (3.14) times radius (8 ÷ 2 = 4) times 2. After that we will divide by two since there is only half. After that we will multiply that answer by three.
C = 3.14 x 4 x 2
C = 12.56 x 2
C = 25.12
C = 25.12 ÷ 2
C = 12.56
Perimeter = 12.56 x 3 = 37.68
Step 2: To find the perimeter of the rectangle/square add all the sides (8).
Perimeter = 8 + 8 + 8 + 8 = 32
Step 3: Now add the two previous answers to get the final perimeter.
37.68 + 32 = 69.68
Final Answer: 69.68
Hope this helped!
Cheers,

Answer: Choice D) Angle Angle Side (AAS)</h3>
Explanation:
The marked angles in red are a congruent pair of angles. This forms the first "A" in "AAS".
The vertical angles are another pair of congruent angles. This is the other "A" in "AAS".
The tickmarks indicate those segments are the same length, so that forms the "S" in "AAS".
The sides are not between the angles mentioned for any given triangle, so we use AAS instead of ASA.
