Roughly, the perimeter of the room, including the sitting area, would be 65.909 ft squared. The perimeter of the semicircle would be approximately 13.909 ft. Then, add it to the 24 (12 x 2) and 28 (14 x 2), and you get 65.909 ft squared. As for the area, it would 168 (12 x 14) + pi (3.1415...) x 6 squared (radius squared - radius is half of the diameter) divided by two (since it's a semicircle). So then, your answer would be about <span>224.54 square feet.</span>
Answer:
1.088 is the answer to the question
Answer:
no , 1 , 3 and 4 are expressions as they don't have an equal sign .
Answer:
okay, so 1 1/6 can be converted to 7/6.
2 3/8 can be converted to 19/8
now find a common denominator, which is 24
7/6 would turn into 28/24
19/8 would turn into 57/24
now add! 28+57= 85/24
85/24

<u>Answer:</u>
x = 20; ∠5 = 120°
<u>Step-by-step explanation:</u>
∠1 and ∠8 are alternate angles and therefore are equal, which means that if m ∠1 = (4x + 40)° and m ∠8 = (2x + 80)°, then 4x + 40 = 2x + 80
Solve for x:
4x + 40 = 2x + 80
2x = 40
x = 20
∠5 is corresponding to ∠1 and vertical to ∠8, therefore equal to both; To find it's measure:
Plug x into either ∠1 or ∠8's respective equations:
2x + 80
2(20) + 80
120
∠5 is 120°
