5*5+5=30
5*5-15=10
30/10= 3
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
First add 10 on both sides. So it will be v = 1.
Answer:
a. 36.25 ft
b. 45 ft
Step-by-step explanation:
