Which of the following statements describes the relation shown in the table below? - -- - (look at the above numbers as if it were a table, and you.) a. it does not have an inverse since it is a relation but not a function b. it does not have an inverse since it represents a function that is not one-to-one. c. it has an inverse since it represents a function that is not one-to-one. d. it has an inverse since it represents a one-to-one function.

180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
