Let’s solve for “a” and “s”.
a = 927 - 45s
a = 792 - 36s
927 - 45s = 792 - 36s
927 - 792 = 45s - 36s
135 = 9s
s = 15
a = 927 - (45 x 15) = 252
Answer:
9x^2+34x+21
Step-by-step explanation:
distribute all the numbers
The diagonals bisect each other
Arc length = 2 π R (C/360)
where:
C is the central angle of the arc
R is the radius of the arc
arc length = 2 π R (137/360) = 2.39R
Answer:
sum of exterior angles of polygon = 360°
therefore,
z = 360 - (105+145)
z = 360 - 250
z = 110°
