Which numbers are rational numbers and irrational numbers and why

-3.786, 3π, 8/17, 8.23, √11, 10.86731234, 0.75, √.49

  rational: -3.786, 8/17, 8.23, 10.86731234, 0.75, √.49 = 0.7

  irrational: 3π, √11

Step-by-step explanation:

Any number that can only be represented completely using symbols, such as π or √, is an irrational number.

If the number can be expressed as the ratio of two integers, it is a rational number. Such numbers include proper and improper fractions, integers, any number you can write with a finite number of digits, and any repeating decimal, regardless of the length of the repeat.

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
