Answer:
360 cm^2
Step-by-step explanation:
First find the area of the bottom
10*10 = 100
The find the area of one of the triangular shapes
A = 1/2 bh since it is a triangle
A = 1/2 ( 10)*13 = 65
Since there are 4 triangles ( 1 for each side), multiply by 4
4*65 = 260
Add the areas together
260+100 = 360
1.06x = 7.95
x = 7.95/1.06
x = 7.5.
The original prices is $7.5

Answer:
see explanation
Step-by-step explanation:
Since the line through A is parallel to BC, then
b = 3 ( alternate angles )
a = 1 ( alternate angles )
a + 2 + b = 180° ( straight angle ), thus
1 + 2 + 3 = 180°
Thus the 3 angles of ΔABC sum to 180°
