Answer:
Step-by-step explanation:
in complementary angle sum of two angle is always 90 degree.so,
let another be x
x+28.1=90
x=90-28.1
x=61.9
therefore another angle is 61.9 degree.
Answer:
5, 7 , 7 and 11.
Step-by-step explanation:
I don't quite understand the Romanian but I'm pretty sure you want to find the numbers whose Lowest Common Multiple is 385 and whose product is 2695. Find the factors of 2695:-
5 2695
7 539
7 77
11
2695 = 5*7*7*11.
Lowest common multiple = 5*7*11 = 385.
Csc x · sec x - tan x =
= 1 / sin x · 1 / cos x - sin x / cos x =
= 1 / sinx cos x - sin² x / sin x cos x =
= ( 1 - sin² x ) / (sin x cos x) =
= cos² x / ( sin x cos x ) =
= cos x / sin x = cot x
The answer for number 1 is `20 because m is -5 since, it is in between 6 and 4. N is exactly 4 so, 4 x -5 equals -20. the expression for the answer 2 is -8 because 2 times negative 4 is negative -8.the expression for #3 is 3 since L is negative 2 and m is negative 5.
