Answer:
3√15/4
Step-by-step explanation:
sin x = 2/8
- from the trigonometric rule sin²x+cos²x = 1
- cos²x = 1-sin²x
sinx = 2/8
sin²x = (2/8)² = 2²/8² = 4/64
1- sin²x = 1-4/64 = 64 -4/64 = 60/64 = 15/16
cos x = √(15/16) = √15 /4
3 x cos x = 3 x √15/4 = 3√15/4
Answer:
25%
Step-by-step explanation:
Given that we have to find what percent of 48 is 12
Let "x" be the required percent
From given statement,
what percent of 48 is 12
Let us say,
x percent of 48 is 12
Writing it mathematically we get,
x % of 48 is 12
Evaluate the above expression to find "x"
Thus 25 % of 48 is 12
