A: smallest
c: largest
b: third
a+b+c=180
a=c/3
b=10+a
solve it
a=34
b=44
c=102
<span> x= Pi, x = 2pi/3, x = 4pi/3
That is the answer</span>
Surface area = 2(ab+bc+ac)
a=5.2 ft, b=2.4 ft, c=3.5ft
Surface area = 2(5.2 * 2.4 + 2.4 * 3.5 + 3.5 * 5.2) =
2(12.48 + 8.4 + 18.2) =
2 * 39.08 =
78.16 ≈ 78.2 ft² ← <span>to the nearest tenth</span>
