Step-by-step explanation:
csc x / (cot x + tan x)
Write in terms of sine and cosine.
(1 / sin x) / [(cos x / sin x) + (sin x / cos x)]
Multiply top and bottom by sin x.
1 / [cos x + (sin²x / cos x)]
Multiply top and bottom by cos x.
cos x / (cos²x + sin²x)
Use Pythagorean identity.
cos x / 1
cos x

Answer:
From the functions f(x) and g(x) we have 
Step-by-step explanation:
Given that the functions f is defined by 
and g is 
To find the 
:
( by using the distributive property )
( adding the like terms )
Therefore .
The arc measure, which corresponds to the central angle measure, is always twice the subtended angle.
So 60 is twice a,
Answer: a=30
84 is twice b
Answer: b=42
60 + 100 is twice c,
Answer: c=80
d is what's left of the circle, total 360 degrees,
d = 360 - 84 - 60 - 100 = 116
Answer: d=116
