___________________________________
height=h=2.29 cm
base=b=4.78 cm
suppose angle is 'O', then,
tanO=2.29/4.78=0.479079
angle O = 25.598 degree
the other acute angle =90 -O = 64.402 degree
The angles of the triangle are,
25.598 degree,64.402 degree and 90 degree

I'm not sure which angle your referring to as theta but it would be the tan-1 (inverse tangent) of the opposite side divided by the adjacent side. so if its the angle adjacent to the base the answer would be tan-1 (2.29 / 4.78)

A triangle has three angles, not angels. Angels are mythological heavenly beings with wings. Triangles don't have any of those, unless they're dancing on one of the angles.

use trigonometry
find the side opposite the angle you are trying to find
call this y
find the side adjacent to the angle....
tan(theta) = opposite/adjacent = y/x
to get theta, we use inverse tan on each side
arctan is another way of saying this its the tan-1 button on ur calculator)
theta = arctan (y/x)

Sorry I don't have an answer-but they don't have angels, they're angles. Keep up the good work.
