Answer: x would have to equal 8
Step-by-step explanation: When a line intersects parallel lines it forms supplementary angles. The sum of two supplementary angles is 180°
We can use this information to set up an equation:
(6x -7 ) + (19x -13) = 180 . Combine like terms
25x -20 = 180 Add 20 to both sides.
25x = 200 Divide both sides by 25
x = 8
Check:
19(8) - 13 + 6(8) - 7 = 180
152 - 13 + 48 -7 = 180
139° + 41° = 180
The sum of the interior angles formed by the line is 180°, so lines a and b must be parallel.
If you are adding the same number in a sequence, then it is arithmetic. If you are multiplying by the same number, it is geometric. Since here you are adding the same number (4), it means that the series <span>1 + 5 + 9 + 13 + 17 + . . </span><span>is arithmetic. </span>
Answer:
x*z-(6)=0
Step-by-step explanation:
Well threw my calculations would be <span><span> x= 0.0000 - 2.0000 i
</span><span> x= 0.0000 + 2.0000 i
