Step-by-step explanation:
What is the maximum angle of a pendulum?
Paul Appell pointed out a physical interpretation of the imaginary period: if θ0 is the maximum angle of one pendulum and 180° − θ0 is the maximum angle of another, then the real period of each is the magnitude of the imaginary period of the other.
In expanded form it is 4 + 0.7 + 0.02
43b)
WCD = (6-2)*180/6 = 120
BCD = (5-2)*180/6 = 108
360-120-108=132 (angle at a point)
CBW = (180-132)/2 = 24 (isosceles triangle)
Answer:
(4, 6 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 36 → (1)
y = - 
x + 8 → (2)
Substitute y = - x + 8 into (2)
3x + 4(- x + 8) = 36 ← distribute and simplify left side
3x - 2x + 32 = 36
x + 32 = 36 ( subtract 32 from both sides )
x = 4
Substitute x = 4 into (2) for corresponding value of y
y = - × 4 + 8 = - 2 + 8 = 6
solution is (4, 6 )
