To test for a triangle, the two smallest sides added together have to be greater than the third side.
3.95 + 4.56 > 8.65
8.51 > 8.65
this is false
4.56 + 8.65 > 10.31
13.21 > 10.31
could be it
4.56 + 8.65 > 13.21
13.21 > 13.21
no, this would mean they're equal
4.56 + 8.65 > 20.25
13.21 > 20.25
this is also false

Answer:
y-intercept: (0, 4)
x-intercept: (20, 0)
Step-by-step explanation:
y-intercept: The y-intercept of a graph is the point where the graph crosses the y -axis. That means, the point in which x = 0.
To find it, we can substitute x by 0 and find y.
x + 5y = 20
0 + 5y = 20
5y = 20
y = 20/5
y = 4
y-intercept: (0, 4)
x-intercept: The x-intercept of a graph is the point where the graph crosses the x-axis. That means the point in which y = 0.
To find it, we can substitute y by 0 and find x.
x + 5y = 20
x + 5*0 = 20
x = 20
x-intercept: (20, 0)
Finally, the graph of the equation is:

Answer:
a) θ = 15° b) θ = 15°, 165°
Step-by-step explanation:
a) Given the equation 2 sin(2θ) = 1
sin(2θ) = 1/2
(2θ) = arcsin(1/2)
2θ = 30°
θ = 15°
b) To find all the solutions between 0 and 2π, we will make reference to the quadrant.
Sinθ is positive in the first and second quadrant.
In the first quadrant, θ = 15°
In the second quadrant, θ = 180°-15°
= 165°
The solutions between 0 and 2π are 15° and 165°
