To find the total measure of the angles in a polygon, the formula is 180(n-2) n being the number of sides in the polygon.
So the correct answer is B) 180(14-2)
Y= -1/4x + 4.25, perdendicular then it must be the opposite of 4x which is -1/4. Then you multiply it with 5 and then add or subtract a number so you can find 3. So -1/4× 5 + 4.25= 3. Here you gooo!

Step(1)
To find q(a) we just need to put a instead of x in q(x) function.
Let's do it...
Multiply sides by -2 :

Step (2)
To find q(a+1) we just need to put a+1 instead of x in q(x) function.
Let's do it...

Step (3)
And we're done.
Thanks for watching buddy good luck.

Alright so if I do remember my math correctly, this is how it goes:
- y = -x^2 + x + 3
- x = -b/2a
- x = -1/2(-1)
- x = -1/-2, which = (1/2)
Not quite sure if this was correct, but if it was, hope this helps and you're welcome! :)
This is a question of proportions:
First we can work out how many feet it goes up for each feet he steps back:
5.5/6 ft per each feet he steps back.
Now we can multiply this by the amount of ft back the cliff is:
(5.5/6)*30 = 27.5 ft
Thus the cliff is 27.5 ft tall,
Hope this helps :)
