A triangle with 3 different sides. One is 16, 17 and 29 . What is the smallest angle of this triangle . Round to neatest hundredth

Sagot :

Answer:

27.57 degrees to neares thundredth.

Step-by-step explanation:

The smallest angle is opposite the smallest side.

Use the Cosine rule

16^2 = 17^2 + 29^2 - 2*17*29 cos x         (where x is the required angle).

cos x = (17^2 + 29^2 - 16^2) /  2*17*29

         = 0.88641

x = 27.574
