A.
because the total distance of every triangle 180. Add the two other angles so 42+ 57 =99. Then you have to subtract those two combined angles to find the missing one from the total distance, which is 180. 180-99=81. the answer is A. 81
Answer:
The length of the other leg is 8.94 m.
Step-by-step explanation:
Given that,
Hypotenuse of a right triangle is 12 m
The length of the one of the legs of a right triangle is 8 m
We need to find the length of the other leg. It is based on the concept of Pythagoras theorem. Let the other leg is h. So, according to this theorem,

H = hypotenuse = 12 m
b = base = 8 m

So, the length of the other leg is 8.94 m.
Answer:
has two terms without any negative exponent. so it is a polynomial.
Step-by-step explanation:
A polynomial is a expression with more than one terms.
The expression with negative exponent is not a polynomial.
Expression in the denominator is also not a polynomial
has two terms without any negative exponent. so it is a polynomial.
option B,C and D has negative exponents, so it is not a polynomial.
