Answer:
Option A) m∠RNS=27°
Step-by-step explanation:
We know that ∠UNR = 180°. This tells us that the Sum of the enclosed angles should equal 180°, by trigonometry. So the enclosed angles are:
∠RNS =
∠SNT=
∠TNU=
Now let us add all the angles and solve for the value of as follow:
Now lets plug in the value into the expression for angle ∠RNS to find the angle as:
Thus Option A. is the correct answer.
Answer:
$250
Step-by-step explanation:
Total parts:
2+3+9 = 14
500/14 = 250/7
2×250/7 : 3×250/7 : 9×250/7
500/7 : 750/7 : 2250/7
The largest share is 2250/7, the smallest share is 500/7.
Find the difference.
2250/7 - 500/7 = 250
Volume of the cone = (1/3) pi r^2 h
h = 2r so substituting for h:-
V = (1/3) pi r^2 * 2r
V = (2/3) pi r^3
