Question

If 15 cot A= 8, find Sin A and Sec A.​

Answer 1

Answer:

SinA = 15/17 SecA = 17/8

Explanation:

15cotA = 8

cotA = 8/15

thus perpendicular = 15 base = 8 hypotenuse = 17(using Pythagoras  theorem )

thus sinA = 15/17

seca = 17/8

Answer 2

15 cot A=8

cot A=8/15 means base =8 and perpendicular=15

H ^2=P^2+B^2

H^2=15^2+8^2

H^2=225+64

H^2=289

H=√289=17

sinA = P/H

=15/17

secA = H/B

=17/8
