In the triangle abc, if side a is 3, side b is 4 and side c is 5, what is the cosine of the smallest angle?

Cosine of the smallest angle is 4/5.

Step-by-step explanation:

It is given that in the triangle ABC,  side a is 3, side b is 4 and side c is 5.

Sum of squares of two smaller sides.

Sum of squares of largest sides.

Since sum of squares of two smaller sides is equal to sum of squares of largest sides, therefore triangle ABC is a right angle triangle.

Hypotenuse = 5 units.

In a right angle triangle, the smallest angle has shortest opposite side.

Shortest side is a=3 It means angle A is smallest.

Therefore, the cosine of the smallest angle is 4/5.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
