Answer:
Right angled triangle
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.
