5 / (2 * a_2) = tan(35°)

5 / (3 * a_2) = tan(x)

—————

x = 25,02°

γ =9.98°

from tan(35)=5/a1 a1 is obtained

.

now you can make

eta = 35+gam

tan(eta) = 5/(a1 + 0.5a1) …..(*****)

.

arctan(eta) brings eta

.

(*****)

who wants to replace a1 with 5/tan(35)

.

tan(eta) = 5 / (1.5 * 5/tan(35) )

5*tan(35)/7.5 = 2/3 * tan(35)
