The second choice is correct. Given that angle 2 and angle 6 are congruent, the largest in each of the corresponding triangles are vertical angles meaning that two known angles are known in each triangle (and they are equal) which means that the last "unknown" (angles 3 and 7) are congruent. The lines DC and AB correspond with these defined, congruent triangles meaning they are parallel.
The range refers to the value of y for which x is define.
So let y=f(x),
Try making x the subject to obtain,
x is defined for all real values of y greater than
0.
Hence the correct answer is D.
Answer: 6/14 and 42/99
Step-by-step explanation:
That all depends what place you want it rounded to.
Rounding to the nearest tenth, it becomes 32.6 .
Rounding to the nearest whole number, it becomes, 33 .
Rounding to the nearest ten or higher order of magnitude, it becomes zero.
