Given a set, A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} a. List the ordered pairs in the relation R on set A, where (, ) ∈ if and only if = 2
b. List the domain and range of R.
c. Is R irreflexive? Justify your answer

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
