Question

If àsin A=5 and 7cosec A=6sec A The find the value of à

Answer 1

Answer:

6.5853

Step-by-step explanation:

Given

a*sin A=5

7cosec A=6sec A     (1)

from 1

we have

$\frac{7}{sin A}$=$\frac{6}{cos A}$    (2)

from 2 we have

tan A=7/6

so,∡ A=49.398705°

Now,

a*sin A=5

a* sin(49.398705°)=5

a=5/sin(49.398705°)

a=6.5853
