Step-by-step explanation:
- isosceles trapezoid
- trapezoid
- rhombus
- square
- rectangle
- parallelogram
- quadrilateral
- 10x+18+62=180 co interior angle
10x=180-80
x=100/10=10
:.x=10
9.
8x+2=7x+14 corresponding angle of parallelogram are equal
8x-7x=14-2
x=12
10.
4x+4=5x+1 corresponding sides of parallelogram are equal
4-1=5x-4x
x=3
11.
4+3x=19corresponding sides of parallelogram are equal
3x=19-4
x=15/3
x=5
