Explanation / Answer

26) We have given sec(6*theta+170)=csc(2*theta-70)

using cofunction identity sec(6*theta+170)=csc(90-(6*theta+170))

plug this sec(6*theta+170)=csc(90-(6*theta+170)) into given equation

csc(90-(6*theta+170))=csc(2*theta-70)

90-(6*theta+170)=2*theta-70

90-17+7=8*theta

80=8*theta

theta=80/8=10 degrees

An angle theta=100 that makes the statement true
