Answer:
e=9.14
Step-by-step explanation:
e²=a²+b²-2abcosФ
e²=36+25-2(30)cos112
e=√36+25-2(30)cos112
e=9.14
Answer:
Step-by-step explanation:
+ we have
[sin(x)]^2 + [cos(x)]^2 = 1
so [cos(x)]= 1- [sin(x)]^2 = 1- (1/2)^2 = 1- 1/4 = 3/4
Then cos(x) can take one of two values;
+ cos(x) =
then tan(x)= sin(x)/cos(x) = (1/2)/ () =
+ cos(x) = -
then tan(x)= sin(x)/cos(x) = (1/2)/ (- ) = -
Have a good day
Answer:
-3.5
Step-by-step explanation:
Flip the equation so it's 0 - 3.5 which would give you -3.5
