Question

How many triangles can be constructed with angles measuring 60º, 60º, and 40º?

Answer 1

Answer:

Second option

Step-by-step explanation:

One of the most common rules about triangles is that the sum of all three of their degrees add up to a total of 180 degrees.

$180=a+b+c$
$60+60=120$
$120+40=160$
$160$

The total sum of all three given angles only adds up to only 160 degrees not 180 like they're supposed to. Which means the following angles cannot construct a triangle and your answer is the second option or "none."

Hope this helps.
