Question

tan 10+tan 35 +tan 10 +tan 35

Answer 1

Tan 10 + tan 35 + tan 10 + tan 35 =2 tan 10 + 2 tan 35 =2 (tan 10 + tan 35) =2 tan(10 + 35) (1 - tan10 tan35) =2 tan 45 (1- tan10 tan35) =2*1 (1- tan10 tan35) =2 - 2 tan10 tan35 = 2 - 2 * 0.65*0.73 = 2 - 0.949 = 1.051

Answer 2

tan 10+tan 35+tan 10+tan 35
= 2tan 10+2tan 35
=2(tan 10+tan 35)
=2(0.176 + 0.700)
=2(0.876)
=1.752

Hope i helped u :)
