AB is a straight line solve for x please help this quiz is so hard

x = 29

Step-by-step explanation:

Since AB is a perfectly straight line, that means its angle is exactly 180°. Given that, we can tell that the three angles all add up to 180°. If we set the equation to equal 180 by adding all the given angles up, we will find the answer.

64 + x + 3x = 180

Combine like terms.

64 + 4x = 180

Subtract 64 from 180 to get 4x by itself.

180 - 64 = 116

4x = 116

Now get "x" completely alone by dividing both sides of the equal sign by 4.

4x/4 = x

116/4 = 29

x = 29
