Questions
Let r and r' denote the angles inside an equilateral prism, as usual, in degrees. Consider that during some time interval from t = 0 to t = t, r' varies with time as r' = 10 + t2.
During this time, r will vary as (assume that r and r' are in degree)
detailed solution
Correct option is A
In a prism: r+r′=A⇒r=A−r′∴ r=60∘−10+t2=50−t2Talk to our academic expert!
