Answer:
A right triangle is a triangle in which one of the angles is a 90∘ angle. The "square" at the vertex of the angle indicates that it is 90 degrees. A triangle can be determined to be a right triangle if the side lengths are known.

Answer:
5 cars will be on the last ferry
Step-by-step explanation:
If you divide 149 by 8, you get 8.27.
Since each ferry can hold 18 cars, you multipy 18 by 8 which results in 144. Then you subtract 144 from 149 and you get 5 :)
If n is an integer, then cos(n(2<span>π))=1.
Take n=0, cos(2</span>π)=cos(0)=1, n=1, cos(2π)=1, n=2, cos(2(2π))=cos(4<span>π)=cos(0)=1...
If n is not an integer, well, ..... we don't know the value, which depends on the value of n.</span>
