Question

If sin A=3/4, the value of sec A is

Answer 1

Answer:

hope it helps!

This can be done by using a right triangle

Answer 2

Step-by-step explanation:

sin A =3/4

we know that sin = opp/ hypotenuse

4^2 = 3^2 +x ^2

16 -9 = x^2

x= root 7

sec A = hypotenuse / adjacent

secA = 4/ root 7

therefore the answer is 4root 7 / 7
