Answer:
3. None of the above ; 4. Equiangular
Step-by-step explanation:
Question 3. Pentagon.
A is <em>wrong</em>. The polygon is not equilateral, because AB ≠ AE.
B is <em>wrong</em>. The polygon is not equiangular, because ∠A ≠ ∠E.
C is <em>wrong</em><em>.</em> The polygon is not regular, because it is neither equiangular nor equilateral.
D is correct, because the polygon is none of the above.
Question 4. Quadrilateral
A is <em>wrong</em>, because AB ≠ AD.
B is correct, because every angle is 90°.
C is <em>wrong</em>, because AB ≠ AD.
D is<em> </em><em>wrong</em>, because congruent means equal, and there is no other figure to compare.
Answer:
Step-by-step explanation:
The triangle is a 30-60-90 right triangle.
The ratio of the lengths of the sides is:
The order of the sides in the ratio above is
short leg : long leg : hypotenuse
The long leg is sqrt(3) times the length of the short leg.
The hypotenuse is twice the length of the short leg.
Answer:
44cm
Step-by-step explanation:
Formula for circumference, C = 2πr
where r is the radius
r = C / 2π
=
=44 cm
Answer:
first one is rational, second is also rational, third is rational, fourth is rational, and fifth is irrational.
Step-by-step explanation:
Rational numbers are numbers that can be expressed as a fraction or part of a whole number. (examples: -7, 2/3, 3.75) Irrational numbers are numbers that cannot be expressed as a fraction or ratio of two integers. The reason why is an irrational number is bc it's not a perfect square while
equals to 7 and is a perfect square.
