If a triangle has sides 4, 6 and 10 and a 2nd similar triangle has a perimeter of 60, find the 2nd largest side of the 2nd trian

algol13

The first triangle has a perimeter of 4+6+10 = 20.

The 2nd longest side is 6/20 = 3/10 of the perimeter. In the larger triangle, the 2nd longest side will have length (3/10)*60 = 18.

_____
These side lengths mean the "triangle" is a line segment. That is, it has zero area.

What is the measure of one exterior angle of a regular hexagon?<br>a. 60<br>b.72<br>c. 90

Molodets [167]

To find the exterior angle measure we would use the following formula:
$\frac{360~degrees }{number ~of ~sides}$
A regular hexagon has 6 sides so we divide:
360/6 which equals 60
So our final answer would be A. 60
