Answer: Yes they could.
Step-by-step explanation:
The two pairs of sides given are proportional: 3/7 : 9/21
The two triangles have the side:side ratio, meaning they are similar
Because they are similar, their hypotenuses <em>could</em> lie along the same line, not guaranteed, but possible.
If you go through the multiplication table of 3, you can pick out the ones between 5 and 31:
6, 9, 12, 15, 18, 21, 24, 27, 30
Which is 9 numbers. I hope this helps!
Answer:
52ft
Step-by-step explanation:
supplementary angles add up to 180 degrees
angle 1 = x
angle 2 = 8x
x +8x = 180
9x = 180
x = 180/9 = 20 degrees
larger angle = 8*20 = 160 degrees
