Answer:

Step-by-step explanation:

Sin A = 3/4

=> Perpendicular/ Hypotenuse = 3/4

=> Perpendicular = 3

Hypotenuse = 4

Applying Pythagoras rule

Perpendicular square + base square = Hypotenuse square

=> Base square = H square - P square

Base square = 4 square - 3square

= 16-9

Base = √7 units

Now Sec A = Hypotenuse/ base

Sec A = 4/√7

Hope this help

khushi406: thanks
