Answer:

k = 45

angle measures are 45, 90, and 45

Step-by-step explanation:

The sum of angle measures is 180

180 = 45 + 2k + k or

180 = 45 + 3k

subtract 45 from both sides

135 = 3k

Divide by 3

45 = k

Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in the triangle = 180°

Sum the 3 angles and equate to 180, that is

2k + k + 45 = 180

3k + 45 = 180 ( subtract 45 from both sides )

3k = 135 ( divide both sides by 3 )

k = 45

------------

Thus 2k = 2 × 45 = 90

The 3 angles are 45°, 45° and 90°
