The trigonometric ratios, as in:
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent = sin/cos
cannot not still be used as there is no hypotenuse.
However, other trigonometric formulae can still be used:
for example in a triangle where side a is opposite angle A, etc, the sine rule:
sin A/a = sin B/b = sin C/c = 1/2R
or the cosine rule:
a2 = b2 + c2 - 2 b c cos A
(which becomes Pythagoras when angle A is a right angle since COS 90o = 0) are always valid.

How do you know the angle without using a calculator?
To find an angle without using a calculator, you will need to use a trig identity. Determine which angle it is and use its corresponding trig identity.
How do you find the height of a right triangle with only knowing its base and base angle?
You have to use trig. If the base angle is a and base b, the height is b tan(a).
How do you find the other side of a right triangle?
use right triangle trig... sin (angle) = opposite side/hypotunese, cos (angle) = adjacent side/hypotunese, and tan (angle) = opposite side/ adjacent side
Do you have to know three side lengths of a right triangle before you can use trig ratios to find the measure of an acute angle?

How do you find an angle of a right-angle triangle when you have all the lengths - using trigonometry?
(the side opposite the angle) divided by (the side adjacent to the angle) = tangent of the angle (the side opposite the angle) divided by (the hypotenuse of the triangle) = sine of the angle (the side adjacent to the angle) divided by (the hypotenuse of the triangle) = cosine of the angle Once you have the sine OR the cosine OR the tangent of the angle, you can get the measurement of the angle on a scientific calculator, or look it up in a table of trig functions in a book.

Prolem and solution of right triangle?
Pythagorean Theorum. A2+B2=C2 That is the topic of study in trigonometry. Trig gets into the trig functions (sine, cosine, tangent...) and since the subject is quite involved, it can't be adequately explained in this type of setting. However... Imagine a right angle triangle, any right angle triangle (that means a triangle in which one side has 90 degrees but you don't necessarily know any other angle of the triangle. If you want to know a specific angle of the triangle (other than the right angle), you COULD measure two lengths of the triangle and calculate the angle using trig functions. The hypotenuse is the segment of the triangle that is opposite the right angle. To calculate the angle in question, measure the OPPOSITE segment (that means the segment that is furthest from the angle), then measure the hypotenuse (explained above). At that point you divide the length of the opposite segment by the length of the hypotenuse and look up the results in your handy sine table (or use your calculator if it has trig functions) and it will give you the angle. Phew! That was a long explanation, and to go into trig functions any further would require a classroom, but basically that's how you would solve a right triangle question.
What are trig?
Trig ratios or to give them their proper name are trigonometrical rations applicable to right angle triangles and they are tangent ratio, sine ratio and cosine ratio.

What is the measure of the angle B in degrees?
You need to give more information... you're probably going to use a trig identity though.
