On a piece of paper, use a protractor to construct a triangle with angle measures of 100° and 30°.
yanalaym [24]

The third angle measures 50° and all sides have different lengths.

<h3>What is a triangle?</h3>

A triangle is a polygon with three sides and three angles. Types of triangles are<em> isosceles, equilateral, scalene and right angled.</em>

The sum of angles in a triangle is 180 degrees.

A triangle with angle measures of 100° and 30°, let x represent the third angle, hence:

x + 100 + 30 = 180° (sum of angles in a triangle)

x = 50°

Also, all sides have different lengths since all the angles are different.

Given:

angle ECB=51 degrees

=>

angle EOB = 2*angle ECB = 2*51 = 102 degrees = arc EAB


Also given minor arc AB = 72 degrees

therefore

minor arc EA = 102-72=30 degrees

Rewrite –220° in radians. Write the solution as a fraction in simplest form.
son4ous [18]

Answer:

- \frac{11\pi }{9}

Step-by-step explanation:

To convert degrees to radians

radian measure = degree measure × \frac{\pi }{180} , then

radian measure = - 220 × \frac{\pi }{180} ( divide 220 and 180 by 20 )

                           = - \frac{11\pi }{9}
