The length of missing sides x = 5 units and y = 5 units.
<h3>What is Trigonometric ratios?</h3><h3>The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).</h3>
In ΔABC,
AB (Base) = y , BC(Hypotenuse) = , CA (perpendicular) = x
and ∠ABC =
Now,
tan = perp. / base
1 = x /y
x= y .................(i)
again,
sin = perp. / Hypo.
x = 5
put in equation (i), we get
y = 5
Thus, the length of missing side of the given triangle is x = 5 units and y = 5 units.

If I read this right,
you put the numbers where the letters go
2 (8) (-4)
since they are in parenthesis, you multiply them.
= -64

Answer:
D. Dividing both sides of the equal sign by a negative number.
Step-by-step explanation:
The inequality symbol is reversed when an operation is performed that changes ordering. The most usual cases are multiplication or division by a negative number.
For example:
-2 < 1
2 > -1 . . . . multiply or divide both sides by -1
__
These operations are not the only ones that change ordering. Care must be taken when applying functions. f(x) = 1/x and f(x) = cos(x) are functions that potentially change ordering, for instance.
