First subtract 2 revolutions from the - 840 :- (- (840-720) = -120
This gives sin -120 which is in the 3rd quadrant of the unit circle
sin -120 = - sin 60 = - sqrt3/2
Answer:
Hi there!
Your answer is:
B. Identity property
Step-by-step explanation:
The multiplicative identity property of 1, any number multiplied by 1, gives the same result as the number itself. It is also called the Identity property of multiplication, because the identity of the number remains the same
Hope this helps!
Answer:
Yes
Step-by-step explanation:
Yes
because we are given that
LN ≅ XZ ( side)
the picture shows that
LM ≅XY ( side)
and
MN ≅ YZ (side)
By the <u>SSS theorem of congruency</u> we conclude that ΔLMN ≅ ΔXYZ
Answer: The following statement is true about indexes and scales: <em><u>They rank-order the units of analysis in terms of specific variables.</u></em>
<u><em>Indexes</em></u> provides with a way to make a complex measure that iterate consequence for multiple rank-ordered related questions or statements.
<u><em>Scale</em></u> is a type of complex measurement that is combined of several items that have a empirical structure among them.
