Answer 2

Answer:

Step-by-step explanation:

expression is 5cosA+12sinA+12

See, the minimum value of sin(x) and cos(x) is -1 for both ( and ofcourse the maximum value is +1)

So for the expression to take minimum value, sin(x) and cos(x) must take their minimum value i.e. -1.

So substituting that in the eqn we get,

-5 -12 +12

Which gives the answer -5
