What is the length of the hypotenuse and its smallest angle of a triangle whose other lengths are 2.34 cm and 1.64 cm?

If it has an hypotenuse then it must be a right angle triangle then by using Pythagoras' theorem its hypotenuse is 2.86 cm rounded and by using trigonometry its smallest angle is 35.02 degrees rounded.

Is there an analytical way to solve trig functions?

yes. there are certain formulae for solving them. dont remember

Right Triangulum 6.8 cm hypotenuse x 6.5 cm leg x 4 cm bottom.what are the angles?

By the Pythagorean theorem, a right triangle with a hypotenuse of 6.8 cm and one side of 6.5 cm must have the another side of about 2 cm, not 4 cm.

A2 + B2 = C2, where A and B are the two sides and C is the hypotenuse

What is physical interpretation of vector space?

A vector has two properties: magnitude and direction. The representation of a vector is an arrow. The tip of the arrow points to the direction the vector is acting. The length of the arrow represents the magnitude.
