What can you infer about triangle MNP if cos( N )=3/5 and sin( N )=4/5 ?

Right angled triangle

Step-by-step explanation:

The triangle MNP has the cosine ratio of the angle N as 3/5 and the sine ratio of the angle N as 4/5. Note MNP is aright angle triangle.

The cosine ratio of the angle N is expressed as  

cosine N = adjacent/hypotenuse

cosine N = 3/5

The adjacent side of the triangle is 3 and the hypotenuse is 5.

For Sine ratio the ratio is represented as  

sin N = opposite/hypotenuse

sin N = 4/5

The opposite side of the triangle is 4 and the hypotenuse is same as 5.

This means the triangle is a special kind of triangle which means the triangle has one angle as 90° and the sum of the other two angle is equal to 90°.

A triangle with side of 3, 4 and 5 is a right angle triangle.
