how to find the value of x using verticle and supplementary angles

The video tutorial explains how to find the angle of B when given an intersection of two lines and one angle of 130 degrees. It covers two methods: using vertical angles, which are equal, and supplementary angles, which add up to 180 degrees. The tutorial demonstrates how to set up and solve the equation to find the missing angle B, concluding that B is 50 degrees.

What is the relationship between vertical angles?

• They are always different.

• They are complementary.

• They add up to 90 degrees.

• They are always equal.

What do supplementary angles add up to?

• 45 degrees

• 360 degrees

• 90 degrees

• 180 degrees

Which of the following is true about angles on a straight line?

• They are always equal.

• They add up to 180 degrees.

• They are complementary.

• They add up to 360 degrees.

If one angle in a pair of supplementary angles is 130 degrees, what is the measure of the other angle?

• 50 degrees

• 130 degrees

• 100 degrees

• 180 degrees

How do you find angle B if angle A is 130 degrees and they are supplementary?

• Multiply 130 by 2

• Add 130 to 180

• Divide 130 by 2

• Subtract 130 from 180
