Answer: Supplementary Angles
Step-by-step explanation:
Supplementary angles are a pair of angles whose sum is 180°. 45° and 135° add up to 180°. Therefore, the answer is supplementary angles.
The domain of the function is possible values of independant varaible such that function is defined or have real values.
So the expression

is not defined for x = -6 and for x = 1, as expression becomes undefined for this values of x (Denominator becomes 0).
So answer is,

Option B is correct.
The volume in cubic meter of the cuboid with the dimensions length = 12 m , breadth = 10m, height = 4.5 m is 540 m³
<h3 />
<h3>Volume of a cuboid:</h3>
where
l =- length
w = width
h = height
Therefore,
l = 12 m
w = 10 m
h = 4.5
v = 12 × 10 × 4.5
v = 120 × 4.5
v = 540 m³
