Answer:
No solution
Step-by-step explanation:
There are no values of Z that makes this equation true.
It's 29/7 or 4 and 1/7 as the mixed number
Step-by-step explanation:
in a parallelogram, opposite angles are equal..
so C is 4a + 22. and B is 6a - 12.
sum of interior angles in a quadrilateral = 360
4a + 22. + 6a - 12. + 4a + 22. + 6a - 12 = 360
20a + 20 = 360
20a = 340
a = 17
sum of angles on a straight line = 180
B + x = 180
6 ( 17) - 12 + x = 180
102 + × = 180
× = 180 - 102
× = 78
Answer:
the answer is 123 123+156=279.
Answer:
Refer below.
Step-by-step explanation:
We know that central angles are congruent, because it is given. We can say that segments AO, CO, BO, and DO are congruent because ALL RADII OF CIRCLE ARE CONGRUENT. Then by the SAS congruency theorem, we know that triangle AOC is congruent to triangle BOD. Finally, we can conclude that chord AC is congruent to chord BD because:"
