38.5
Step-by-step explanation:
Answer:
180.
Step-by-step explanation:
Given
x = 1%2F2y
x+y=180
...
Substitute x into the second equation and solve for y, the larger angle
1%2F2y + y = 180
Multiply both sides by 2 to be rid of the fraction
y + 2y = 360
3y = 360

Answer:
-2
Step-by-step explanation:
x = r cos θ
y = r sin θ
dx/dθ = -r sin θ + r' cos θ
dy/dθ = r cos θ + r' sin θ
dy/dx = (r cos θ + r' sin θ) / (-r sin θ + r' cos θ)
At θ = π/2, cos θ = 0, sin θ = 1, and r = 1. So the derivative simplifies to:
dy/dx = (r') / (-1)
dy/dx = -r'
dy/dx = -2 sin θ
dy/dx = -2
