Answer:
Step-by-step explanation:
x²+y² = 5²
3²+y² = 25
y² = 16
y = ±√16 = ±4
Since the terminal side is in quadrant IV, y = -4
sinθ = -4/5
Answer:
x = 1
Step-by-step explanation:
the triangles are the same,
7 = 3x + 4
7 - 4 = 3x
3 = 3x
x = 1
hope this helps, please mark it brainliest
4x+y = 20
3x+y = 2
4x+y-3x-y = 20-2
x = 18
3x+y = 2
3.18 + y = 2
54 + y = 2
y = -52
Answer:
(x – h)2+ (y – k)2 = r2
Step-by-step explanation:
572 im pretty sure thats it
