love history [14]

Answer:

Step-by-step explanation:

Remember PEMDAS!

So first parentheses:

1.6^2 = 2.56

8.7 + 9.3 = 18.

Because that is inside another parentheses you multipy them.

2.56 x 18 = 46.08

Now: 46.08 divided by 1.8 = 25.6

Now subtract:

25.6 - 3.7 - 1.9 which equals 20!

Polygon with three interior angles whose sum 180 degrees

mojhsa [17]

Answer:

Triangle

Step-by-step explanation:

A triangle has three vertexes, and therefore three interior angles. Those angles also sum to 180 degrees because of the formula (n-2)*180, where n is the number of sides that a polygon has. Plugging in 3, you get $1\cdot 180$ , or just 180 degrees. Hope this helps!
