Answer:

None

Step-by-step explanation:

The angles inside a triangle add to 180. If the angles are 80, 80 and 40, then they must add to 180 to form a triangle.

80+80+40 = 200

This can't be a triangle.

Zero.

The sum of these angles is 200°. The sum of angles in a triangle must be 180°. These angles cannot be used to form a triangle.

A rectangular piece of tin has an area of 1056 square inches. A square of 3 inches is cut from each corner, and an open box is m

kvv77 [185]

Answer:

44 inches and 24 inches

Step-by-step explanation:

Let $l,b$ denotes length and breadth of a rectangle.

$lb=1056$

A square of 3 inches is cut from each corner, and an open box is made by turning up the ends and sides.

New length $=l-6$ inches

New breadth $=b-6$ inches

Height of box $=3$ inches

Volume of box = length × breadth × height

$(l-6)(b-6)3=2052$

$lb-6l-6b+36=684\\6(l+b)=408\\l+b=68\\b=68-l$

Put $b=68-l$ in $lb=1056$

$l(68-l)=1056\\l^2-68l+1056=0\\l^2-44l-24l+1056=0\\l(l-44)-24(l-44)=0\\(l-24)(l-44)=0\\l=24,44$

At $l=24,b=\frac{1056}{24}=44$ inches

At $l=44,b=\frac{1056}{44}=24$ inches
