A sail in the form of a right triangle the angle at its lower edge is 55 what is the size of the angle formed at the top of the
Mars2501 [29]

Answer:

The size of the angle formed at the top of the sail is 35.

Step-by-step explanation:

We know that the sum of all angles inside a triangle must be 180. This is a rule.

So we know that a right triangle is called like that because one angle is a 90-degree angle.

Then we have that:

180 = right angle + lower edge angle + angle top of the sail

180 = 90 + 55 + angle top of the sail

Solving for 'angle top of the sail' we have:

angle top of the sail = 180 - 90 - 55 = 35

The size of the angle formed at the top of the sail is 35.

Do 2 or more shapes with the same perimeter have to have the same area? Explain with examples. AND Do 2 or more shapes with the
Murljashka [212]
Yes. Take for example a square and an ellipsis with the same perimeter. The family of ellipses with the same perimeter can have any area between that of a circle to zero (if it is extremely “thin” i.e. if its eccentricity is large). The circle has the maximum area of any other shape with the same perimeter, so the square has the same area of one of the intermediate ellipses.
