Answer:
angles are 40 and 50
Step-by-step explanation:
let angles be 4x , 5x
4x + 5x = 90
x= 90 / 9
x= 10
angles are 4x , 5x
therefore angles are 40 , 50
Answer:
ANSWER ' A '
x - 4y = 8
Step-by-step explanation:
arcsin(1) = 90 degrees
arccos(1) = 0
arctan(1) = 45 degrees
When you say "arcsec(1)", do you mean the angle whose secant is 1 ?
Since the secant is 1/cosine, if the secant of your angle is 1, then
its cosine is also 1, and the angle is zero (and 360).
