How do I figure angles in a right triangle.?

Question

Sorry, but I am 71 years old that this has left me.
I want to figure the two unknown angles in a right triangle.
AB is 2
BC is 5
and of course angle B is 90

Might as well remind me how to figure the hypotenuse.

You can use:

x being the angle
tan x = opposite/adjacent
tan x = 2/5
x = arctan(2/5)
x = 21.8


for the hypotenuse, Pythagorean Theorem:
a^2 + b^2 = c^2

In your case:

2^2 + 5^2 = c^2
4+25=c^2
sqrt(29) = c

as lone ranger was told by tonto

The sons of the squaw on the hippopotamus is equal to the sum of the sons on the other 2 hides

or the square of the hypotunus is equal to the sum of the squares of the other 2 sides

a^2= b^2 + C^2
