Cos=adjacent/hypotenuse
Cos30=x/20
x=cos30 *20
Sorry I don’t have a calculator right now
Answer:
3/50
Step-by-step explanation:
It's not as hard as you might think! You can just multiply the denominator and numerators separately. So in this case, you just need to do 9*1 and 25*6. This means that the answer is just 9/150, simplify it and you get, 3/50!
Answer:24
Step-by-step explanation:
Múltiply 3(2)(2)(2)=24
So, first you divide 75000 by 1000. Then you add 2 to each side. Then that's the answer, x=77
Answer:
CSA of cylinder = 704cm²
We know that
CSA of cylinder = 2πrh
or 2πrh = 704
or, 2*22/7 *8 *h = 704 ( since r=8cm)
or, 352h = 704*7
or, h = 4928/352 = 14cm
