Answer:
Perimeter of the given figure = 28 units
Step-by-step explanation:
Perimeter of the given figure = Length of AB + Length of BC + Length of CD + Length of DE + Length of EF + Length of FG + Length of GH + Length of AH
Length of AB = 4.5 units
Length of BC = 2 units
Length of CD = 2 units
Length of DE = 4 units
Length of EF = 5.5 units
Length of FG = 1.5 units
Length of HG = 1 units
Length of AH = 7.5 units
Perimeter of ABCDEFGH = 4.5 + 2 + 2 + 4 + 5.5 + 1.5 + 1 + 7.5
= 28 units

Answer:
Step-by-step explanation:
complementary angles, when added, equal 90 degrees
so if 1 angle is x, then the other angle, its complement, is 90 - x.
x - 18 = 90 - x
x + x = 90 + 18
2x = 108
x = 108/2
x = 54
90 - x = 90 - 54 = 36
so one angle is 54 and its compliment is 36
