Answer:

similar

Step-by-step explanation:

Similar triangles have equal angle measures.  The sum of the angles of any triangle must add up to 180°.  Since the angles of ΔDEF are 80° and 40°, then the third angle must be 60°:  80 + 40 = 120; 180 - 120 = 60. Also, the angles of ΔABC are 60° and 40°, which makes the third angle 80°: 60 + 40 = 100; 180 - 100 = 80.  Given that ΔDEF and ΔABC both have angles of 40°, 60° and 80°, then they are similar.

Maru [420]
The answer would be 10.19m. If you want to round it of to a less precise measurement it would be 10 m. That is rounding of the decimal value to the ones place. the rule of rounding of is form 6 t0 9 it would add 1 to the nearest place value next to it and 0 - 5 will not.

Which property of polynomial addition says that the sum of two polynomials
ArbitrLikvidat [17]

Answer:

The property of polynomial addition that says that the sum of two polynomial is always a polynomial is called closure property of addition or under addition.

Polynomials are closed under addition because when you add polynomials the letters and their exponents do no change, you just add the coefficients of the like terms (those with same letters raised to the same exponents), so the result will be other polynomial of the same kind, except for the terms that cancel (positive with negative) which does not change the fact that the result is still a polynomial.

In mathematics the closure property means that the result of an operation over a kind of "number" will result in a "number" of the same kind.
