Answer:
triangular prism
0.5 X 5 X 4 X 9 = 90 cubed cm
cuboid
6 X 5 X 20 = 600 cubed cm
triangular prism : cuboid
90:600
now simplify
both are divisible by 30
3:20
this cannot be simplified further
answer = 3:20
180=9×w
length=9
width=20
perimeter=58

Answer:
<h3>Q1</h3>
Angles forming a linear pair are supplementary and sum to 180°
- x + 8x = 180°
- 9x = 180°
- x = 20°
The smaller angle is 20°
<h3>Q2</h3>
A(-2, 10) reflected over x-axis
<u>Rule for such a reflection is:</u>
<u>Point A will map to:</u>
Correct option is D
<h3>Q3</h3>
One point is at the origin and two other points are at the distance m horizontally and vertically from the origin
<u>The last point will have same distance m from the point (m, 0) and (0, m) and this will be point:</u>
