Answer:
a=4 n=25
Step-by-step explanation:
5a+5=n
(a+n)-4+25
a+n=29
5(4)+5=n
20+5=25
Sin = - 4/8
Quadrant IV = only cosine is positive
a = height (4)
b = base ( 8^2-4^2=b^2
b = 6.93 @

c = hypothenuse(8)
cos =

/8
tan = - 4/

sec = 1/cos
1/cos = 1/ (

/8)
sec = 8/

csc = 1/sin
1/sin = 1/(-4/8)
csc = - 2
cot = 1/tan
1/tan = 1/(-4/

)
cot = -

/4
