For sake of abbreviation I will use A for measure of angle A, B for measure of angle B, etc.

Since A-C=15=>A=15+C

A+B+C=180=>

15+C+75+C=180=>

90+2C=180=>

2C=90=>

C=45 degre

**Hence angle C measure 45 degree.**

angle A+B+C = 180

B = 75

A+C = 180-75 = 105

A-C = 15

Add above two

2A =120

A = 60

C = 45
