Answer:
the answer is 12.2
Step-by-step explanation:
thats what i got
Note that
sin(30°) = 1/2
cos(30°) = √3/2
tan(30°) = 1/√3
cos(45°) = 1/√2
tan(45°) = 1
Therefore
5 sin²(30°) + cos²(45°) - 4 tan²(30°)
= 5*(1/4) + 1/2 - 4*(1/3)
= 5/12
= 0.4167
2 sin(30°) cos(30°) + tan(45°)
= 2(1/2)(√3/2) + 1
= 1.866

Answer: 0.223
answer is polygon is a quadrilateral, then the polygon has only four sides
Try this one, too: "If the quadrilateral has four congruent sides and angles, then the quadrilateral is a square." Converse: If the quadrilateral is a square, then the quadrilateral has four congruent sides and angles.
Answer:
A
Then that gives you -n=2
Than u multiply it by -1 to get rid of the negative n, giving you the final answer of n=-2
