Answer:

x= 8

y = 21

Step-by-step explanation:

27 + 3y = 90

3y = 90 -27

y = 63/3

y = 21

x+ 90 +8x+18 = 180. { linear pair}

9x +108 = 180

9x = 180-108

x= 72/9

x = 8

Calculate the perimeter to the nearest tenth​
fomenos

Answer: the perimeter is 40.9 ft

Step-by-step explanation:

The given figure is a trapezium. It is made up of a rectangle and a right angle triangle.

The perimeter of the trapezium is the distance around the figure. This means that the inner dimensions are not included.

Since the opposite sides of the rectangle are equal, it means that the base of the trapezium would be

10 + 4 = 14 ft

Therefore, the perimeter of the trapezium would be

8 + 10 + 8.9 + 14 = 40.9 ft
