Answer 1

Answer:

tan17° tan35° tan45° cot(90-55)°cot(90-73)°

=

tan17° tan35° tan45° cot35°cot17°

=

tan45°=1

Answer 2

Answer:

Step-by-step explanation: Tan 17* tan 35 * tan 45* tan 55* tan 73

arrange them

tan17*tan 73*tan 35 tan*55 tan*45

=tan(90-73)tan73*tan(90-55)tan55*tan45

=cot73*1/cot73*cot55*1/cot55*tan45

=1*1*1=1

.... mark as brainly ? xd

tan theta=1/cot theta note it
