A triangular plot of land has sides 205 m, 195 m, and 120 m. Find the measure of the smallest angle.

1 answer:

4 0

Using Law's of Sine and with the given three sides of the of the triangle, we can solve for the smallest angle. The smallest angle is opposite of the smallest side. Solution is below:
a=120, b= 195 and c=205
cos A = (B²+C²-A²)/2BC
A=inverse (195²+205²-120²/2*195*205)
A=inverse 0.8211
A=34.8°
Therefore, the answer is letter B which is 34.8°.

Let \[f(x) = \frac{3x - 7}{x + 1}.\]find the range of $f$. give your answer as an interval.

Hello :
let : $y= \frac{3x-7}{x+1}$
calculate : x ......x <span>≠ -1
</span> $y(x+1) = 3x-7$
$yx+y =3x-7$
$yx-3x = -y-7$
$x(y-3) = -7-y$
$x = \frac{y+7}{3-y}$
the inverse function is : $g(x) = \frac{x+7}{3-x}$
domain of : g is the range of : f
as an interval : ]-∞: 3 <span>[</span>U ]3;+∞[
