Given that lines a and b are parallel, angles 1 and 5 are congruent because they are corresponding angles, and angles 1 and 4 are congruent because they are vertical angles. then, by which property are angles 4 and 5 congruent? together, these statements prove which theorem?

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

hi! i think the answer is 1/2 : )

x = 3 ± √(5+y)

add 8+12 to get a simplified answer of 12r-20
