Step-by-step explanation:
sin(x/2) = sqrt((1 - cos(x))/2)
cos(x/2) = sqrt((1 + cos(x))/2)
tan(x/2) = sin(x/2)/cos(x/2)
sin(x) = 15/17
so, we can assume the Hypotenuse of the right-angled triangle is 17, the vertical leg is 15.
via Pythagoras we get the 3rd, horizontal side :
17² = 15² + side²
289 = 225 + side²
64 = side²
side = 8
cos(x) = 8/17
sin(x/2) = sqrt((1 - 8/17)/2) = sqrt(9/34) = 3/sqrt(34) =
= 0.514495755...
cos(x/2) = sqrt((1 + 8/17)/2) = sqrt(25/34) = 5/sqrt(34) =
= 0.857492926...
tan(x/2) = 3/sqrt(34) / 5/sqrt(34) = 3/sqrt(34) × sqrt(34)/5 =
= 3/5 = 0.6
Answer:
Step-by-step explanation:
The given equation is
Subtract 2 from both sides and factor by grouping to get:
By the zero product principle:
When
This implies
When
We have
hence x is not defined for all real numbers
well u have to find the different of 360-356 which would be=4 and if u were going to round it to the tenth then it would be 4% still
Answer:
y = 8
Step-by-step explanation:
simplify=9y-12=60
add 12 9y=72
divide 9y/9= y= 72/9=8
please mark branliest i really need it.
