Use the Rectangle to the right for Questions 1-4

1. 34

2. 56

3. 112

4. 68

Step-by-step explanation:

For the first one, the angle measuring 112 is a vertical angle to angle 9 so angle 9 is also 112. So 180-112 (180 because the measure of every triangle is 180.) is 68. Then you divide 68 by 2 and get 34 because the angles 1 and 8 measure the same.

For the second one, you would first find the measure of angle 10 by subtracting 180-112 again and getting 68 (the measure of a flat line is 180.) Then you would get 112 for the remaining angles and divide that by two because once again, the two angles are the same measure. So 112 divided by 2 is 56.

For the third one, I already stated that the measure of angle 9 is 112.

And finally, for the fourth one, I also previously stated that the measure of angle 10 is 68.
