Answer:
3) B) 90°
4) A) 75°
Step-by-step explanation:
3) interior angles of a triangle =180°
So
40+50+?=180
? =180- 90
? =90
4) same rule
40+65+?=180
? =180 - 105
? = 75
The minimum thickness of the book would simply be the sum
of the thickness of the two cover pages and all the pages in between. That is:
minimum thickness = 0.9 mm * 2 + 0.13 mm * 400
<span>minimum thickness = 53.8 mm</span>
I don't know what you mean by "critical points". However, I'm going to list all the important points in this equation-
x intercepts: (-1 ,0) and (5,0)
vertex: (2,-9)
y intercept: (0,-5)
Hope this helps!
