Question

sin A + COS A
20 Given 5 cos A - 12 sin A = 0, find the value of
2 cos A - Sin A​

Answer 1

Answer:

5 cos A = 12 sin A

.'. Your question says sin A + cos A = sinA + 12/5 sinA = 17sinA / 5

Also,  2cosA - sinA = 24/5 sinA - sinA = 19 sinA/5

Dividing both, we have:- (sin A + cos A)/(2cosA - sinA) = 17 / 19

Step-by-step explanation:

Answer 2

Answer:

5cosA−12sinA=0

tanA=

12

5

Now,

2cosA−sinA

sinA+cosA

Multiply and divide by cosA

= tan A+1/2-tanA

=5/12+1/2-5/12

=5+12/12/24-5/12

=17/19
