Question

Prove that 2tan50-tan70+tan20=0​

Answer 1

Step-by-step explanation:

block of mass m is placed on smooth inclined plane of incilation tetha with the horizontal. The dorce exerted by the plane on the block

Answer 2

Step-by-step explanation:

tan 50=1.19175359259

Therefore, 2( tan50)=2.38350718519

tan 70=2.74747741945

2tan50-tan70=

2.38350718519-2.74747741945

= - 0.36397023426

tan 20 = 0.36397023426

2*(tan 50)- tan 70 + tan 20=

0.36397023426 - 0.36397023426

=0

LHS=RHS

Hence Proved
