The complete question is shown in the figure below. As you can see one square units is well shown in the graph. So we can conclude that the distance between two consecutive points is 1 unit. If so, then we can calculate the area of the parallelogram as follows:
Then, finding CB by Pythagorean Theorem:
And:
Therefore:
Answer:Side x side x side
Step-by-step explanation:
Since it is usually equally sided, it would be SxSxS
The total angle sum of a triangle is 180°
As such, 180= 78 + 2s +4s
102= 6s
s=17
$76.80 minus 12 1/2 is $64.30.
