Find the exact value of tan 2x if sin x = -4/5. (Quadrant III)

sin x = -0.8

x = -53.13010235 (used inverse of sin)

tan 2x

tan -106.2602047

= 0.61854704132

2nd one in the first row is correct

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to
