mina made the shape below by putting together an equilateral triangle and a square.?
what is the sum of the interior angles of the shape Mina made
a square with a triangle on top they both are missing one side
it kind of looks like a house
90° + 90° + 150° + 150° + 60° = 540°
Another method :
It is a pentagon ( a five sided polygon)
Sum of internal angles of n-sided polygon is (n - 2) * (180°)
For n = 5, it is (5 - 2) * (180°) = 540°.

Where is the "shape below" as mentioned?

I think you should count the sides and then use the formula (n-2)180. The n is for number of sides.
