Question

given 15 cot A = 8, find only sec a​

Answer 1

Answer:

15Cot A=8

Cot A=8/15

Cot=Base/Perpendicular

so Base=8

Perpendicular=15

USE PYTHAGORAS THEOREM TO FIND HYPOTENUSE..

AND THEN PUT ITS VALUE FOR SEC A

which is equal to HYPOTENUSE/BASE

Answer 2

Answer:

15 cot A=8

CotA= 8/15

Cot= Base/perpendicular

sec= Hypotenuse/Base

now we have to find Hypotenuse

by Pythagoras theorem

$h ^{2} = b ^{2} + p ^{2}$

=64+225

=289

h=√289

h=17

secA= 17/8
