Answer:

Associative Property of Addition

Step-by-step explanation:

Here, in the second line, there are plus signs (+'s), indicating this is addition. But this time, unlike the first line, the numbers are grouped together with parentheses. When numbers are grouped with parentheses, it means it is the Associative property. Because we are adding, it's the associative property of ADDITION.

Hope this helped!

The Measure of the largest angle of a triangle is 40° more than the measures of the smallest angle, and the measures of the rema
gtnhenbr [62]

Answer:

40, 60 and 80 degrees.

Step-by-step explanation:

Let the smallest angle be x degrees. Then:

The 3 angles are x, x + 40 and x + 20.

As there are 180 degrees in a triangle:

x + x + 40 + x + 20 = 180

3x = 180 -40--20 = 120

x = 40 degrees.

The other 2 angles are  60 and 80 degrees.
