One interior angle of a triangle is 45°, and the other two angles are congruent. Choose the equation that could be used to determine the degree measure of one of the congruent angles.

x + 45 = 180
x − 45 = 90
2x + 45 = 180
2x − 45 = 90

Answer:

Step-by-step explanation:

x  and  x = other two angles  

       ('congruent' means the two angles are equal in measure)

x   and   x   and   45   aded together =   180°  

     (  because the sum of the angles of any triangle = 180)

so:

  x + x + 45 = 180     simplify to:  

  2x + 45 = 180            Done.
