Isosceles triangle
so
x + 8 = 2x -1
x = 9
BC = 3x - 3
BC = 3(9) - 3
BC = 27 - 3
BC = 24
Answer:
3
Step-by-step explanation:
its 3 because the line goes through 3 on x axis of the graph
Answer:
so you got ehffffffffff
Step-by-step explanation:
In degrees: 3π/4 radians = 135°
Angle of x=135° is in the 2nd Quadrant and has negative cos x values and positive sin x values.
cos 135° = cos ( 90° + 45°)= - sin 45° =

sin 135° = sin ( 90° + 45° ) = cos 45° =
