Answer:
Please check the explanation below.
Step-by-step explanation:
As we know that quadruple is basically a fourfold amount or number.
For example,
The quadruple of 6 is 24.
4 x 6 = 24
Similarly, the quadruple of 10 is 40.
4 x 10 = 40
Now, let me solve your query.
Given the expression
2 - 2
as
2-2 = 0
so
we have to determine the quadruple of 0.
i.e.
4 x 0 = 0
Therefore, 0 is the quadruple of 2-2 (or 0).
I hope, it has cleared your concept.
The value of y is positive 8
A^2 = b^2 + c^2 - 2bc cos a
= 11^2 + 5^2 - 2*5*11 cos 40
= 7.86 to 2 DP's
to find the remaining angles use the sine rule:-
a / sin A = b / sin B so
7.857/ sin 40 = 11 / sin B
sin B = 11 sin40 / 7.857 = 0.8999
<B = 64 degrees
so <C = 180 - 64-40 = 76 degrees
