Question

10.
The greatest value of the function 7 sin A - 24 cos A is :
(1) 12
(2) 13 (3) 25
(4) 17 ​

Answer 1

Answer:sum value of sin and cos are 1

So replacing sin theta and cos theta by one it will become 12+5=17

Answer 2

Answer:

25

explanation:

maximum value of (a sin A - b sin B) = √a²+b²

therefore,

=√7²-24²

=√49+576

=√625

=±25

hence;

the maximum value is +25
