(Round if needed.) Do not use commas or spaces.

1. Two angles of a triangle have measures 51° and 72°. Find the measure of the third angle in the triangle. Enter your answer as an integer, without the degree sign.

2. One angle in a triangle has a measure of 29°. The difference between the other two angles is 55°. Find the measure of all angles in the triangle. Enter the measure of the greatest angle in the triangle, without the degree sign.

3. Find the value of x based on the picture below.

4. Consider triangle ABC. The measure of angle A is three times the measure of angle C, and the measure of angle B is twenty-five degrees less than the measure of angle C. Find the measure of the angles in this triangle.

 Angle A = Angle B = Angle C =

5. Consider triangle ABC. The measure of angle B is five degrees less than twice the measure of angle A. The measure of angle C is five degrees greater than three times the measure of angle A. Find the measure of the angles in this triangle.

 Angle A = Angle B = Angle C =
