Answer: C
Step-by-step explanation: your fast answer is C.
Cos Z = 32/40 => Z= cos-¹(32/40) =>
sin Z = sin (cos-¹(32/40)) = 3/5
Answer:
12
Step-by-step explanation:
(25-16) / h = h / 16
9/h = h/16
=144 ( 9 x 16)
h₂ = 144
h= square root 144
h= 12
Answer:
-5/4 or -1.25
Step-by-step explanation:
the points are (-6, -3) and (-2, -8)
the formula for slope is y2-y1/x2-x1
y2 is -8
y1 is -3
x2 is -2
x1 is -6
(-8+3)/(-2+6)
(-5)/(4)
-5/4 or -1.25
The answer is Hx = ½ Wsin θ cos θ
The explanation for this is:
Analyzing the torques on the bar, with the hinge at the axis of rotation, the formula would be: ∑T = LT – (L/2 sin θ) W = 0
So, T = 1/2 W sin θ. Analyzing the force on the bar, we have: ∑fx = Hx – T cos θ = 0Then put T into the equation, we get:∑T = LT – (L/2 sin θ) W = 0
