It all depends upon what other things are given If hypotenuse is not given, in cosine or reciprocals are useless. In that case only tan and cot will be equally convenient if adjacent sides are given.
So I would give you the answer but I don’t know it
Step-by-step explanation:
the writing and spacing of the problem description is difficult to understand.
but there is no mystery. look at the examples.
all of them
3×5 = 15 = 16 - 1 = 4² - 1
4×6 = 24 = 25 - 1 = 5² - 1
5×7 = 35 = 36 - 1 = 6² - 1
6×8 = 48 = 49 - 1 = 7² - 1
7×9 = 63 = 64 - 1 = 8² - 1
8×10 = 80 = 81 - 1 = 9² - 1
so, what does this look like ?
(x-1)×(x+1) is always equal to (x² - 1)
Answer:
A= 45 degrees
And angle B= = 135 degrees
Step-by-step explanation:
Supplementary means that the sum of both angles is equal to 180 degrees.
< A= x
< B= 3x
<a+<B= 180
x+3x= 180
4x= 180
x= 180/4
x= 45
Therefore angle A= 45 degrees
And angle B= 3x= 3*45= 135 degrees
