7p = 28....division property...divide both sides by 7
p = 28/7
p = 4 <== there are 4 players
Answer:
<d = 25 degrees and <e = 130 degrees
Step-by-step explanation:
We have a vertical angle, so the opposite sides of this angle are the same. This means that the angle opposite to 25 degrees also measures 25 degrees. We have one angle of the triangle. Since the triangle is isosceles, the angle d is the same as 25 degrees.
<d = 25 degrees
The interior angles of a triangle add up to 180 degrees, and we now have 2 angles, so:
<e = 180 - 25 - d
<e = 155-25
<e = 130 degrees
60 inches because the square has 4 sides so 4x2 is 8 and 52+8 is 60.
Use A' for A complement, etc. and n = intersection ∩.
n(A' n B')
=n(A u B)' by the de Morgan's law
=nU-n(nA+nB-n(AnB)) n(A u B) = nA + nB - n(AnB) and nX'=nU-nX
=400-(135+80-60)
=400-155
=245
Answer:
(64/5)π units²
Step-by-step explanation:
The area of this sector would be:
Given central angle
------------------------------ *(area of whole circle)
2π rad
In this case, the area of the sector is:
(8/5) π rad
------------------------------ * π(4 units)^2
2π rad
and this reduces to:
(4/5) * π*16 units² or (64/5)π units²
