I will teach you the procedure and make a calculation, based on a hypothetical dimension.
Call x the length of the side.
You will obtaind two equilateral triangles from a square if you cut by the diagonal.
The length of the diagonal is x√2.
If the sign is placed with the diagonal as the base and the vertex up (this is the righ angle), then the heigth is half the diagonal, i.e. (x√2) / 2.
So, if the side of the square is 100 inches, the diagonal is 100√2 and half diagonal is 50√2, which to the nearest tenth is 70,7 in.
This shape would be an equilateral triangle, hope that helps!!
Put parentheses around the '6 + 12 ÷ 6' and another parentheses around the '6 + 12':-
8 x 5 - ((6 + 12) ÷ 6)
= 40 - (18 ÷ 6)
= 40 - 3
= 37
He must sell more than $1058. First find the difference and multiply that by 20 (100/5) to find the necessary amount.
It has infinite solution or many solutions.
The steps are on paper.
