If A lies in the third quadrant and `tanA=4/3` then find the value of `sinA+cosA`

If A lies in the third quadrant, and 20tanA = 21, then the value of (5 sin A-2 cos A)/(4cosA-5/7 sinA) is: यदि A तीसरे चतुर्थाश में स्थित है तथा 20tanA= 21 है, तो (5 sin A-2 cos A)/(4cosA-5/7 sinA) का मान क्या होगा ?

If A lies in the second quadrant and 3tanA + 4=0 , then find the value of 2cotA-5cosA+ sinA .

If A lies in the first quadrant and 6tanA = 5, then the value (8 sinA -4 cosA)/(cosA + 2 sinA) is : यदि A प्रथम चतुर्थाश में स्थित है तथा 6tanA = 5 है, तो (8 sinA -4 cosA)/(cosA + 2 sinA) का मान क्या होगा ?

If A lies in the third quadrant and 3 tan A- 4 =0, then 5sin2A + 3 sinA + 4cosA=

If A lies in the second quadrant and 3tanA+4=0 , then the value of 2cotA-5cosA+sinA is

If A lies in the second quadrant and 3tanA+4=0 , then the value of 2cotA-5cosA+sinA is

If A lies in the third quadrant and 3 tan A-4 = 0, then 5 sin 2A + 3sinA + 4 cosA is equal to
