given triangle JKL with JK = 10, m∠J = 20, which of the following choices is used to determine the length of KL?

tan J

Step-by-step explanation:

From the given trinagle;

JK = Adjacent = 10

KL = Opposite

JL  = Hypotenuse

m<J = 20degrees

Using the SOH CAH TOA identity

tan theta = opp/adj

tan m<J = KL/JK

tan 20 = KL/10

KL = 10tan20

Hence tan J can be used to determine KL

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
