Since a square has four sides you divide 215 by 4 your answer will be 53.75
Each side 53.75 long
Answer:
146°
Step-by-step explanation:
The measure of the arc EF is equal to the angle subtended at the centre.
That is EF = 146°
To ease your problem, consider "L" as you x-axis
Then the coordinate become:
A(- 4 , 3) and B(1 , 2) [you notice that just the y's changed]
This is a reflection problem.
Reflect point B across the river line "L" to get B', symmetric of B about L.
The coordinates of B'(1 , -1) [remember L is our new x-axis]
JOIN A to B' . AB' intersect L, say in H
We have to find the shortest way such that AH + HB = shortest.
But HB = HB' (symmetry about L) , then I can write instead of
AH + HB →→ AH + HB'. This is the shortest since the shortest distance between 2 points is the straight line and H is the point requiered
Answer is $22.37:
You subtract $56.75 from $87.37,which equals $30.62, then you add the 2 checks that the bank didn't return and subtract that amount from the $30.62.
An obtuse angle is an angle that is in between 90 degrees and 180 degrees. It looks like this
