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.

Answer:
x=2√5
Step-by-step explanation:
<u>1st method:</u>
sin(30)=opposite/hypotenuse=√5/x
sin(30)x=√5
x=√5/sin(30)
x=2√5
<u>2nd method:</u>
cos(60)=adjacent/hypotenuse=√5/x
cos(60)x=√5
x=√5/cos(60)
x=2√5
<u>3rd method:</u>
This is a 30-60-90 triangle, so we can multiply the short side, √5, by 2, to get x=2√5
Just by simply adding the two quantities you can get the net change. $67.12 +(addition sign because we want the net change) $2.56= $69.68. The last number is the net change!
