What is the area of this figure?

MissTica

Okay so here's what you do. The arrows mean the the sides are the same length so the > line is 20in. And then they cut this up into 2 triangles and a trapezoid. BUT If you look closely 1 of the Triangles and the Trapizoid make a Parallelogram. The formula for finding the area of a Paralellogram is just b*h. So then you just need to find the area of the other triangle which would be 8*20/2 (the formula is b*h/2 for triangles) and then you add those to answers together. (So it's 20*16+8*20)

The shortest distance between the airport A and airport B travels by airplane which departs airport A at a heading of 300 (N 60 W) is 401 miles.

<h3>What is the law of cosine?</h3>

When the two sides of and one angle is known, then to find the third side, the law of cosine is used.

It can be given as,

$c^2=a^2+b^2-2ab\cos C\\a^2=c^2+b^2-2ab\cos A\\b^2=a^2+c^2-2ab\cos B$

Here, a,b and c are the sides of the triangle and A,B and C are the angles of the triangle.

An airplane departs airport A at a heading of 300 (N 60 W). After traveling 320 miles, the airplane adjusts its course to 350 (N 10 W) and flies an additional 112 miles to reach airport B.

The image of this problem is attached below. In this image, the two sides 112 miles and 320 miles are shown and the angle between them is 130 degrees. Thus, the value of x is,

$x=\sqrt{112^2+130^2-2(112)(130)\cos 130^o}\\x=401\rm\; miles$

Hence, the shortest distance between the airport A and airport B travels by airplane which departs airport A at a heading of 300 (N 60 W) is 401 miles.
