Quiz 1 - Angles In a Triangle


For each of the following question, enter your answers as an integer.
(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 =
