Find the measure of angle 3

Mathematics
1 answer:
Oksana_A [137]4 years ago
8 0
This Shape is a Pentagon. Five sided figure.

There are 5 angles at a point. The sum of the 5 angles is 360.

Let each angle be x.

5*x = 360

x = 360/5

x = 72

The perpendicular divides the central angle 72 into 2 equal parts.

72/2 = 36

Angle 3 + 36 + 90 = 180        Sum of angles in Triangle

Angle 3 + 126 =  180

Angle 3 = 180 - 126

Angle 3 = 54 degrees.

Interpret (1,15)<br><br> interpret (4,60)
statuscvo [17]

Interpreting (1,15) with (4,60), found that (4,60) is 4 times of the coordinate (1,15).

<h3>What are coordinates?</h3>

A pair of numbers that describe the position of a point on a coordinate plane by using the horizontal and vertical distances from the two reference axes.

For interpreting we have to find the relation between (1,15) and (4,60)

We have, (1,15)

For x- coordinate 1, y- coordinate will be 15

Now,

let us take x- coordinate=2 then y- coordinate =30

again, if x-coordinate = 3 then y-coordinate  = 45

lastly, if the x-coordinate =4 then y-coordinate = 60

That means (4,60) is the 4 times of the coordinate (1,15) i.e., the x-coordinate is 4 times as well as the y- coordinate is 4 times.
