Triangle A B C is shown. Angle C A B is a right angle. Angle A B C is 30 degrees and angle B C A is 60 degrees. The length of A

marishachu [46]

Answer:

i. sin(C) = $\frac{\sqrt{3} }{2}$

ii. tan(C) = $\sqrt{3}$

iii. sin(B) = $\frac{1}{2}$

Step-by-step explanation:

Given a right angled triangle ABC, with a right angle at A.

<ABC = $30^{0}$

<BCA = $60^{0}$

AC = 9 = 1

CB = 18 = 2

Applying Pythagoras theorem to ΔABC, we have;

AB = $\sqrt{BC^{2} - AC^{2} }$

= $\sqrt{2^{2} - 1^{2} }$

= $\sqrt{3}$

Thus applying the trigonometric ratios, it would be observed that;

i. sin(C) = $\frac{\sqrt{3} }{2}$

ii. tan(C) = $\sqrt{3}$

iii. sin(B) = $\frac{1}{2}$

The radius of a 12 inch right circular cylinder is measured to be 4 inches, but with a possible error of ±0.2 inch. What is the

GuDViN [60]

Given:
r = radius = 4
h = height = 12
dr = error in radius = 0.2

What we want to find
dV = error in volume

Use the derivative to find the differential dV
V = pi*r^2*h
dV/dr = d/dr[ pi*r^2*h ]
dV/dr = 2pi*r*h
dV = 2pi*r*h*dr
dV = 2pi*4*12*0.2
dV = 19.2pi

So if the error in measuring the radius is +-0.2 inches, then the error in the cylinder volume is +-19.2pi cubic inches (we either measure the volume to be 19.2pi cubic inches too big, or 19.2pi cubic inches too small)

----------------------------------------------------------------------------------

Final Answer: Plus or minus 19.2pi cubic inches

Note: your teacher may want you to drop the "plus or minus" part
