in the stair railing shown at the right, if <6 has a measure of 130°. find the measures of the other three angles.

- 5 and 6 is in the same line, a line measures 180°.
- 6 measures 130°.
- 8 and 6 are congruent to each other.
- Since 8 and 7 is on the same line.
- 8 measures 130°, We only need to find the measure of 7 to make 8 and 7
supplementary.
