Hello!
Here we are given a composite shape, meaning that we can divide this shape up into ways that we are given formulas to solve for legs and such.
I can see here that this can be divided into a triangle and a rectangle using a horizontal line.
The leg lengths of this triangle would be 9, because it is congruent to the bottom side of the rectangle, and 7, because it is the left side minus the right side.
This would also make a right triangle, meaning we could solve for the hypotenuse utilizing the Pythagorean Theorem.
Which is in simplest radical form.
Hope this helps!

Answer:
105
Step-by-step explanation:
It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
(91+89+X)/3 =95
91+89+X =95*3
180+X =285
X =285 - 180
=105
Answer:
7 Rows with one row having 6 Chairs. The other 6 Rows will have 8 chairs each.
6x8 = 48 chairs + 1x6 = 54 chairs.
Step-by-step explanation:
1 Row = 8 Chairs [1Row/8Chairs]
(1Row/8Chairs)*(54Chairs) = (54/8) Rows = 6.75 Rows
The manager needs 7 rows, one row will have only 6 chairs [(0.75 Rows)*(8Chairs/1Row) = 6 Chairs
