Diagram, line bc is parallel to de. i. e bc de abc = 42 cab = 109 find falls

x = 29°

Step-by-step explanation:

Since line BC is parallel to line DE, therefore:

m<BAD = 42° (alternate interior angles are congruent)

m<BAD + m<BAC + x = 180° (angles on a straight line)

42° + 109° + x = 180° (substitution)

151° + x = 180°

Subtract 151 from each side

x = 180 - 151

x = 29°

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
