x= r - h/y subtract r from both sides
x-r = -h/y multiply each side by -y
-y(x-r) = h
-xy +yr = h
Answer
10a mean 10 x a
Find the number when you times gives you 100,000
a= 10,000
Answer:
360 degrees
i know this because i skate on a skateboard
The arc length of a subtending arc on a circle has the formula:
s = r<span>θ
where is the arc length
r is the radius
</span><span>θ is the angle subtended
</span>
So,
θ = s/r = 8π / 4.5 = 16<span>π/9
We multiply it with 180/</span><span>π to convert it to degrees.
</span>(16π/90) (180/π) = 320<span>°</span>
