Answer:
Mrs. Fowler will get 
free pizza. And she needs two more coupon for the next pizza.
Step-by-step explanation:
Given that pizza stand gives a free pizza for every 
coupons.
And Mrs. Fowler has 
coupons.
Part (a)
How many free pizzas can Mrs. Fowler get if she has coupons?
We will divide total number of coupons by coupons.
When we divide we get quotient as , with a remainder of 
. So, Mrs. Fowler will get free pizza.
Now, part (b)
If Mrs. Fowler adds two more coupons that will turn remainder into 
.
So, she can have next pizza.
Answer:
Suppose that you had a right angle triangle. Note that if you take it and another copy of it (moved around a bit) the two triangles together can be placed to make a rectangle.
This rectangle has four 90 degree angles adding up to 360 degrees. Since the triangles are congruent each triangle has half as many degrees, namely 180. So this is true for any right triangle.
Suppose you triangle is not a right triangle. Draw a perpendicular from the vertex opposite the longest side, to the longest side. What you have now is two right triangles which, by the above contain 360 degrees in total. But if you look at the two right angles that add up to 180 degrees so the other angles, the angles of the original triangle, add up to 360 - 180 = 180 degrees.
Step-by-step explanation:
Well I think the scale is number 7 because
