This is a relatively easy question if you know a couple things, so let me walk you through this step by step ok?
<em>Answer: 115°</em>
<h3>
Sum of interior angles of a pentagon: 540°</h3>
Now with that said:
<em>
</em>
Your first step is to add all of the interior angles together, and then subtract it from the total sum of the interior angles of the shape that your working with.
If you don't know what the sum of all of the interior angles are for the shape you are working with, you can easily look it up on google to be sure.
<em>If you have anymore questions, </em>Don't be afraid to ask! I'm always glad to help, also if I am wrong please let me know and I promise I will come back and rework my math.

Answer:
x-4y = 8
Step-by-step explanation:
y– 1 =1/4 (x – 12)
Multiply each side by 4
4y -4 = x-12
Subtract x from each side
-x +4y -4 = -12
Add 4 to each side
-x+4y -4+4 = -12 +4
-x+4y = -8
Multiply by -1
x-4y = 8
Answer:
266
Step-by-step explanation:
Let the attendence of 5days be a,b,c,d,e
given,
(a+b+c+d+e)/5=264
a+b+c+d+256=264*5 [since 5th day=256]
(a+b+c+d+)/4=1(320-256)/4 [dividing both side by 4]
average attendence of 4 days =266
Answer:
The second bubble
Explanation
You need to make your exponents equal the other side so to do this;
Distribute the 3 in the exponent "3(x-2)"
Which is 3x-6
And since multiplying exponents adds them, you need a -6 to make the two equal.
So your exponent should equal -6 to make that statement true
Cuboid has 6 faces. If each face was 2m squared, that would be 2m squared times 6 which is 12m squared
