A , B and C = The angles of a triangle

A = 110 °

The angles of a triangle always sum to 180 °

A + B + C = 180 °

110 ° + B + C = 180 °

B + C = 180 ° - 110 °

B + C = 70 °



B / C = 5 / 9 Multiply both sides by C

B = 5 C / 9


B + C = 70 °

5 C / 9 + C = 70 °

5 C / 9 + 9 C / 9 = 70 °

14 C / 9 = 70 ° Multiply both sides by 9

14 C = 70 ° * 9

14 C = 630 ° Divide both sides by 14

C = 630 ° / 14

C = 45 °

B = 5 C / 9

B = 5 * 45 ° / 9

B = 225 ° / 9

B = 25 °
