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:
The largest angle is 63
Step-by-step explanation:
Shows that one is 36 degrees larger: 63 - 36 = 27
Shows that the angles are complementary/Their sum is 90: 27 + 63 = 90
<h3>Given:</h3>
angle CED = 45°
angle EDC = x
angle DCE = 2x
<h3>To Find:</h3>
The value of x.
<h3>Angle Sum Property:</h3>
The sum of all the Interior Angles of a triangle is 180°.
<h3>Solution:</h3>
x + 2x + 45° = 180°
or, 3x = 180° - 45°
or, 3x = 135°
or, x = 135/3 = 45°
<h2>Answer:</h2>
The value of x is 45°.
