Question

If tan a is equal to 3 by 4 then what is value of sec a

Answer 1

Answer:

TanA=3/4

secA=?

TanA=opposite/adjacent

opp=3

adj=4

hyp=5

secA=hypotenuse/adjacent

so,

5/4

how hypotenuse we got 5 is

hyp square =opp square +adj square

H square=9+16

=25

=√25

=5

Answer 2

Answer:

Given tan A = 3/4

Answer: sec A = 5/4

Step-by-step explanation:

tan A = opposite side/adjacent side

sec A = 1/cosA

i.e., sec A = Hypotenuse/adjacent side

opposite side = 3

adjacent side = 4

hypotheses = 5 (by Pythagoras theorem)
