I am looking for the same answer if anyone knows it
4th quadrant is positive x (cos) and negative y (sin)
Use the Pythagorean Theorem to calculate the value of y (sin).
x² + y² = c²
5² + y² = 13²
25 + y² = 169
y² = 144
y = 12
Since the y-value is negative in the 4th quadrant, then y = -12
Answer:The slope is 1
Step-by-step explanation:
y2-y1=-3
x2-x1=-3
put them into a fraction and the slope is 1 because -3/-3=1
Becouse k and n are 'neighbours' so their sum are 180
so k=180-42=138
Answer: 2.1925153x10 to the 3rd
Step-by-step explanation: hope it helps
