Question

17. If sinx = -4/5 and x lies in third
quadrant then find the value of tanx +
secx.​

Answer 1

Answer:

Step-by-step explanation:

sinx = -4/5 and x lies in third quadrant

then

tanx = 4/3                                              by pythagarous law and

secx = -5/3                                             common trignometric formulas

put in eq  tanx + secx

we get,

4/3-5/3  =  -1/3
