Asail 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 sail? choise 15 or 25 or 30 or 35 or insufficient information

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.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
