3tg(-π/4) + 2sin(-π/6) - 5agπ/4

To simplify this expression, we first need to determine the exact values of tan(-π/4) and sin(-π/6).

tan(-π/4) = tan(-45°) = -1
sin(-π/6) = sin(-30°) = -0.5

Substitute these values into the expression:

3(-1) + 2(-0.5) - 5agπ/4
= -3 - 1 - 5agπ/4
= -4 - 5agπ/4

Therefore, the simplified expression is: -4 - 5agπ/4
