__________________________________________--
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

you didnt specify which acute angle, because there are two, and because the height and base arent equal, the angles wont be either.
but this will do
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)

Tan (theta) = 2.29cm ÷ 4.78cm
