Z + Y = a right angle so need to equal 90 degrees:
Find Z & Y:
2b + 6 + 3b -1 = 90
5b +5 = 90
5b = 85
b = 85/5
b = 17
Z = 2(17) +6 = 34+6 = 40 degrees
Y = 3(17) - 1 = 51 - 1 = 50 degrees
Y & W make a straight line so need to equal 180:
W = 180 - 50 = 130 degrees.
Z & X make a straight line so need to equal 180:
X = 180 - 40 = 140 degree.
answer
i
explanation
note that i = and that

=
= i
note that the i is outside of the square root

#22 you just figure out the common denominator, then figure out from there and #24 i dont understand
Answer:
540°
Step-by-step explanation:
A pentagon has 5 sides
therefore number of sides, n = 5
Sum of interior angles of a polygon = (n - 2) 180
Slot in the values
(5 - 2) 180
3* 180
= 540°
