Explanation:

<CDB = 1 + 6x

<DCB = 58°

<CBF = 11x + 9

Now

<CBF = < CDB + < DCB ( Exterior angle of a triangle is equal to the sum of two opposite interior angles )

11x + 9° = 58° + 1° + 6x

11x - 6x = 59° - 9°

5x = 50°

x = 10°

<C = 58°

<D = 1 + 6 * 10° = 61°

< B = 11 * 10° + 9 ° = 110° + 9 = 119°

Hope it will help :)
