Ответ:
x = 60/4
x = 15so the student studied 15 minutes per day
Ответ:
3.62 units
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between the side adjacent to the angle and the hypotenuse:
Cos = Adjacent/Hypotenuse
cos(34°) = AB/AC
AC = AB/cos(34°) = 3/cos(34°) ≈ 3.619 ≈ 3.62 . . . units
For right triangle ABC with A an angle of 34°, AB of length 3, and AC the hypotenuse.
