Ayellow line means traffic on either side may cross the center line to pass another vehicle. a. single solid b. double solid c. single broken d. double broken

Single broken along with a single solid yellow line means traffic on either side may cross the center line to pass another vehicle .

Option - C

Explanation:

Traffic signals are to be followed to protect us from accidents and making accidents. If rules are followed as per the signals there will be smooth flow of traffic on the either side of the road.

One mistake by a person may lead to fatal accidents. To overtake a vehicle you have to do it at the right point where the traffic lines are drawn. For that purpose the Single broken yellow line is the point where the other vehicle can overtake.  

If we are driving on side of the broken yellow line we are allowed to overtake the other vehicles. But if we are driving on the side of solid yellow line, we cannot overtake.

if triangle abc is congruent to triangle def, their interior angles are congruent, because congruent parts of congruent triangles are congruent (cpctc).

that means ∠d is congruent to ∠a; ∠d is equal to 8x - 2.

interior angles of all triangles add to equal 180 degrees, so you can set the sum of these interior angle values equal to 180 and solve for x.

180 = (8x - 2) + 22 + 72

180 = 8x - 2 + 22 + 72

180 = 8x + 92

88 = 8x

11 = x

x = 11
