Answer:

60 square km

Step-by-step explanation:

First, seperate the figure into two as a rectangle and a trapezium by drawing a line from the vertex between the lines which are 8km and 5km long until it reaches the line on the bottom. (11km) Then, find the area of the rectangle by multiplying 8 by 6, which gives an answer of 48 square km. Then, find the area of the trapezium using the equatiuon 1/2 (a+b) h. Here, a and b are the two parallel lines of the trapezium, which are the lines 2km and 6 km long, and h means the perpendicular height which is 3km long (by substracting 8 from 11, you get 3). you get the answer as 12 square km. finally, add up 12 and 48 to get 60 square km.

Mhanifa please help :( no one has helped me on this yet

Answer:

16)

  • q / 12 = sin 20
  • q = 12 sin 20
  • q = 4.1
  • p / 12 = cos 20
  • p = 112 cos 20
  • p = 11.3

17)

  • x / 44 = tan 39
  • x = 44 tan 39
  • x = 35.6
  • 35.6 / y = sin 39
  • y = 35.5 / sin 39
  • y = 56.4

18)

  • 14 / b = sin 57
  • b = 14 / sin 57
  • b = 16.7
  • a / 16.7 = cos 57
  • a = 16.7 cos 57
  • a = 9.1

A parallelogram should have 2 sets of parallel lines. Let's find the slope of line PQ and RS to test.

PQ:
(4-2)/(1-(-3))
2/4
1/2

RS:
(2-0)/(3-1)
2/2
1

Because 1 does not equal 1/2 (the slopes are different) the lines are not parallel. Thus, the figure is not a parallelogram.
