lines de and ab intersect at point c. what is the value of x? 12 25 38 52
Answer
Explanation:
Step1: Use the property of vertical angles
Vertical angles are equal. So, (2x + 2+5x + 3 = 180) (since they are linear - pair adjacent angles, and the sum of angles on a straight line is (180^{\circ})). Simplify the left - hand side: (7x+5 = 180).
Step2: Solve the linear equation for (x)
Subtract (5) from both sides: (7x=180 - 5), so (7x = 175). Divide both sides by (7): (x=\frac{175}{7}).
Answer:
(25)
