Answer:
∠C = 90°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
6x + 2x + 4x = 180, that is
12x = 180 ( divide both sides by 12 )
x = 15
Hence
∠C = 6x = 6 × 15 = 90°
Answer:
(1) is a function, surjective aka onto,
not bijective aka one to one.
domain is {3,6,12,14,20,22},
range is {4,15,8,11}. More elements in domain means it can't possibly be one to one.
(2) is a relation but not a function, although its inverse is a function. There are fewer elements in the domain than the range, so a function could not be onto but would have to be into or injective.
The relation you get by restricting the domain to {1,19} is a function, injective, so that the image of the domain is a proper subset of the range.
