Step-by-step explanation:
According to the questions statements it shows
y= L sin (theta)
and as it shows A and B are right triangle
y= sqrt (L^2 - x^2)
we need to find the speed of B by differentiating w.r.t time.
so,
d/dt = dx/dt . d/dx = -v d/dx
-v represents the A's velocity
so,
Vb = d/dt (y) = -v d/dx sqrt(L^2-x^2)
= v.x/ sqrt(L^2-x^2)
x/ sqrt(L^2-x^2) = cot (theta)
hence
Vb = vcot (theta)
Step-by-step explanation:
= 2x + 10x - 15
=12x - 15
I think this is the answer
Answer:
97 degrees
Step-by-step explanation:
We know that U and W add up to 180 degrees so we can write:
8x+9+8x-5=180
Simplify:
16x+4=180
We can figure out x from here!
x=11
Since x=11, we can plug that in and get:
88+9=97
