Find the measure of exterior angle A. Show equations and all work that leads to your answer.

Morgarella [4.7K]

Fine but I ain't showing my work completely.

The sum of all ext. angles of a polygon = 360.

So, you make this formula and solve for x.

360 = 49 + (3x+30) + (14x+6) + (6x-3) + (4x+8)
360 = 49 + 27x + 30 + 6 -3 + 8
360 = 90 + 27x
270 = 27x
/27 /27
10 = x

Now substitute for angle A, which is (6x-3)
6x-3
6(10)-3
60-3
57

Therefore, angle A is 57 degrees.

A park is in the shape of a rectangle. The park authorities are planning to build a 2-meter-wide jogging path in the park (shown

Burka [1]

First, we need to find the area of the two rectangles in this picture. We know that area = l*w.

So for the larger rectangle, we know the l = 100 m, and the w = 60 m. Let us find the area:

$A=100*60=6000 m^{2}$

So the larger rectangle area is 6000 m.

The smaller rectangle has dimensions that are 2 m less on every side. So we can recalculate these dimensions as l = 96 m and w = 56 m.

Let's find the area of the smaller rectangle:

$A=96*56=5,376 m^{2}$

So we know that the area of the smaller rectangle is 5,376 m.

The area of the jogging path is going to be the difference between these two rectangles. Let us solve:

$6,000-5,376=624 m^{2}$

So now we know that the area of the jogging path is $624 m^{2}$ .
