Choice D will create an irrational number when added. This is because a rational number plus a rational number will always be irrational (you can experiment this by trying to add rational numbers to pi). For example, 3 + pi = 6.1415926..... or

Answer:
B
Step-by-step explanation:
Angles in a triangle add up to 180
Take 45 + 90 then subtract the answer from 180
<span>The length of an arc, L = theta/360 * 2 * pie * r
Where theta = 81 and r = 10ft = 3.048m
So length = 81/360 * 2 * pie * 3.048
L = * 0.225 * 2 * pie * 3.048
L = 1.37 * pie
L = pie. Option A</span>
Answer:
Step-by-step explanation:
First, on the right-hand side of the equation, let's distribute the 
to each term in the parenthesis:
Now, let's move all the terms with an 
to the left-hand side, and everything else to the right-hand side of the equation:
Let's combine like terms:
Finally, let's divide each side by 
to get by itself on the left-hand side of the equation:
Surface are has a formula which is
SA=L*w+W*h+L*h
