If a scalene triangle has its measures 4 m, 11 m and 8 m, find the largest angle.

soldier1979 [14.2K]

Answer:

129.8 approximately

Step-by-step explanation:

So this sounds like a problem for the Law of Cosines. The largest angle is always opposite the largest side in a triangle.

So 11 is the largest side so the angle opposite to it is what we are trying to find. Let's call that angle, X.

My math is case sensitive.

X is the angle opposite to the side x.

Law of cosines formula is:

$x^2=a^2+b^2-2ab \cos(X)$

So we are looking for X.

We know x=11, a=4, and b=8 (it didn't matter if you called b=4 and a=8).

$11^2=4^2+8^2-2(4)(8)\cos(X)$

$121=16+64-64\cos(X)$

$121=80-64\cos(X)$

Subtract 80 on both sides:

$121-80=-64\cos(X)$

$41=-64\cos(X)$

Divide both sides by -64:

$\frac{41}{-64}=\cos(X)$

Now do the inverse of cosine of both sides or just arccos( )

[these are same thing]

$\arccos(\frac{-41}{64})=X$

Time for the calculator:

X=129.8 approximately

Is it true or false? And how

olasank [31]

The answer is false.

Counterexample:

If a = 4 and b = 2

(4 - 2)^2 = 4

4^2 - 2^2 = 12

Since these answers are not the same this equation is false.

If I have a cylinder, the radius is 9.3 ft and the height is y, the volume of the whole thing is 3000ft, then what does y equal?

disa [49]

Answer:

Step-by-step explanation:

r = 9.3 ft

h = y ft

Volume = 3000 ft

πr²h = 3000

3.14 * 9.3 *9.3 * y = 3000

$y = \frac{3000}{3.14*9.3*9.3}\\\\$

y = 11.05 ft
