Answer:
Step-by-step explanation:
I assume that you mean
sec(x)-tan(x) = 1 / ( sec(x) + tan(x) ) , right ?
then this is equivalent to
[ sec(x) - tan(x) ] x [ sec(x) + tan(x) ] = 1
let s evaluate it, we got
sec2(x) - sec(x)tan(x) + - sec(x)tan(x) - tan2(x) = sec2(x) - tan2(x)
= (1 - sin2(x) ) / cos2(x) = cos2(x) / cos2(x) = 1
as cos2(x) + sin2(x) = 1
First you find 4/5 of 8 and then 4/5of 7 and multiply them
The shape of a dice is a cube. A cube is a shape which is 3D. A cube has 6 squares which makes it 3D. A dice has dots on them. The dots stand for numbers. Each side has a different number. They have up to 6 dots.
Hope I helped ya!!!☺☺☺
Answer:
=>1
=> 
=> Simplify:minus and minus simplify each other and so do 3 and 3
=> So were are left with 1
Thus,the answer is 1
