-72=-9s-45 also equals -9s-45=-72
-9s - 45 + 45 = - 72 + 45
-9s = - 27
-9s/-9 = -27/-9
s = 3
Hope this helped!
Write and solve an equation of ratios:
5 65
--- = ------
4 x
Then 5x = 260, or x = 52. There are 52 girls on the team. Note, as a check, that 65/52 reduces to 5/4, as it must.
5682 divided by 4 is 1420 remainder 2 Hope that helped Have a good day! :-)

Answer:
They are not similar.
Step-by-step explanation:
The angles of a triangle add up to be 180°. If they were similar, the triangle angles would have to be 60°, 40°, and 80°. Because one of the angles is 81°, the triangles cannot be similar.
81° + 40° + 60° does not equal 180.
