Angle θ lies in the fourth quadrant, and cot θ = -8/15 sin θ = cos θ =

Sin θ =   and .

Step-by-step explanation:

Given  : cot θ = -8/15.

To find : sin θ  and cos θ.

Solution : We have given

cot θ = .

cot θ =  .

=  .

Hypotenuse =

Hypotenuse = .

Hypotenuse =   .

Hypotenuse =   .

Hypotenuse =17 .

Sin θ = .

Plugging the values.

Sin θ =   .

Cos θ =  .

Cos θ =  .

Therefore, Sin θ =   and .

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
