Savatey [412]

Answer:

Step-by-step explanation:

Given a triangle with two sides a and b and an included(an angle between the two given sides) angle $\theta,$

Area of the Triangle $=\dfrac12 ab\sin \theta$

$a=32$ miles\\b=23 miles\\\theta =37^\circ$

Therefore, The area of the portion that will not be farmed

$=\dfrac12 \times 32 \times 23 \times \sin \37^\circ\\=221.47\\\approx 221.5$ square miles$

The correct option is C.

The height of a triangle is 4 inches. Greater than twice it's base. The area of the triangle is no more than 168 in.². Which any

mestny [16]

Step-by-step explanation:

this problem seeks to test our knowledge on word problems and algebra

<u>Solution</u>

let the base be x, and

the height h = 2x+4

We know that area of a triangle is given as

$A= \frac{1}{2} b*h$

substituting our given values we have

$168= \frac{1}{2} x*(2x+4)\\\\168= \frac{2x^2+4x}{2} \\\\168= x^2+2x\\\\$

re-arranging we have

$x^2+2x-168=0\\\\$

we can now find two factors that will add up to give 2 and multiply to give -168

they are 14 and -12

$x^2-14x+12x-168=0\\\\x(x-14)+12(x- 14)=0\\\\x+12=0\\\\x=-12\\\\x-14=0\\\\x=14$

The possible base of the triangle is 14 in

and the height is

$h= 2x+4\\\\h=2(14)+4\\\\h= 28+4\\\\\h= 32 in$
