The four corners of a square are 90 degrees.
They are evenly split by the diagonal lines, so each corner is now two 45 degree angles.
The lines form triangles, which have 3 angles that need to equal 180 degrees.
Two of the angles are 45, so 45 + 45 = 90 degrees.
X = 180 -90 = 90 degrees.
Step-by-step explanation:
this is the answer in the picture
Answer:
let m be minutes, p be pages
pages read = times(in minutes) * reading speed(pages per minutes)
p=m*(60/20)
p=3m
For every increase of a minute of reading time, pages that Wesly have read will increase by 3
I think you meant "y = 4 arccot (x)."
This is equivalent to:
y
---- = arccot x
4
and so cot (y/4) = x
