Which number produces an irrational number when add to

The sum of any two rational numbers is a rational number. 0.166, 2/3, and 2 are all rational numbers, so adding them to 1/3 will produce another rational number.

That leaves 2π, an irrational number. The sum of a rational number and an irrational number is always irrational, so 2π will produce an irrational number when added to 1/3.

a: inscribed angles

step-by-step explanation:

i reviewed this question with a peer and teacher, seems to be correct, me later

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
