Answer:
hen two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal. ... Two angles are said to be supplementary when the sum of the two angles is 180°.
Step-by-step explanation:
Answer:
rational : square root of 81, 7/16, square root of 36
irrational : pi, square root of 48, square root of 120
Step-by-step explanation:
7. y = 1, AB = 1, BD = 10 and AD = 11
8. x = 5, AB = 20 and BC = 20
9. x= 5 and AB = 33
10. No, because AC = 12.5 while AB + BC = 20 (they should equal the same and they don't.)
Equation~ 5b + (2b - 4) + (3b -6)= 180.
the answer is 5

really all you have to do is multiply 126 * 2 * 7 * 3
then all that's next is to just put the letters in the order they were originally at the end of the answer
