Given m∠B = 62, m∠C = 54 and line AD bisects ∠BAC, find m∠ADB
insens350 [35]
THE ANSWER IS: 86 degrees

first find the measure of angle a: since all angles of a triangle add up to 180, add the measures of angle b and angle c then subtract it from 180 to get angle a: 62+54=116, 180-116=64

since we know line AD bisects angle a, we can divide 64 degrees by 2 to find angle BAD: which is 32 degrees

then subtract both 62 and 32 from 180 to get 86 degrees for angle ADB

Water is drained out of tank, shaped as an inverted right circular cone that has a radius of 16cm and a height of 8cm, at the ra
andriy [413]
Let h=height of water
Let r=radius of water surface
r/h=16/8 =2, so r=2h.
The volume of water is:
v=(1/3)×π×r²×h
=(1/3)×π×(2h)²×h
=4/3πh³
dv/dh=4πh^2
By chain rule:
dv/dt=dv/dh×dh/dt
but
dv/dt=4 
thus:
4=(4πh)×dh/dt
dh/dt=4/(4πh²)
when h=6cm we have:
dh/dt=4/(4π6²)
=0.00884 cm³/min
