Answer:
x = 136°
Step-by-step explanation:
The opposite angles of a cyclic quadrilateral are supplementary, that is
x + 44° = 180° (subtract 44° from both sides )
x = 136°
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.
Answer:
220
Step-by-step explanation:
Here you go the answer is p=-2
(i wrote p as x so just change all the x with p)
Using proportions, it is found that both patterns have the same number of ovals.
- This question is solved by <em>proportions</em>, using rule of three.
For Phil:
- 1 of each two shapes is oval, hence:
1 oval - 2 shapes
x oval - 96 shapes
Applying cross multiplication:



For Stacy:
- 2 of each two shapes are oval, hence:
2 oval - 4 shapes
x oval - 96 shapes
Applying cross multiplication:



Both patterns have the same number of ovals.
