Step-by-step explanation:
Check the picture below.
for "b", well, recall that the sum of all interior angles in a triangle is 180°.
for "a", "c" and "d", well, all those are just <u>intercepted arcs</u>.
Just use your right angled triangle formula.

A=71.5
Answer:
rectangular tables
Step-by-step explanation:
x: how many tables
a) 49x/49=800/49
x=16.3
so roughly 16 tables
b) 64x/64=800/64
x= 12.5
so roughly 12(you round to nearest even number when it is .5)
c) Now we will calcuate how many people will fit using the number of fitting capacity
=16 (8)
128
=12(12)
=144
Therefore, the rect tables will fit more people
Answer: x^2 + 4x + 4
Explanation:
just expand, factor out, and add together.
(x+2)(x+2)
x • x = x^2
2x + 2x = 4x
2 • 2 = 4
x^2 + 4x + 4
