two parallel lines are crossed by a transversal. what is the value of x? x = 40 x = 70 x = 110 x = 130
Answer
Explanation:
Step1: Use the property of supplementary angles
When two parallel lines are cut by a transversal, the sum of adjacent angles on the same side of the transversal is (180^{\circ}). So, (x + 70=180).
Step2: Solve for (x)
Subtract (70) from both sides of the equation: (x=180 - 70).
Answer:
(x = 110)
