If you're only given the base, then you can't calculate the other leg. If you have any one of the following, then you can calculate all of the parts of the triangle: -- length of the other leg -- length of the hypotenuse -- size of either acute angle
Providing it's a right angle triangle the formula is: hypotenuse2-base2 = height2
With Pythagoras' theorem or trigonometry depending on the information you are given.
The measure of only one angle and one side is not sufficient to calculate the lengths of the sides of a triangle. If you have one more angle or one more side you can use the sine rule.
(base x height) / 2
Height will be h=base*tan(angle).
By using the tangent ratio of: opposite/tangent angle = adjacent which is the base
If you're only given the base, then you can't calculate the other leg. If you have any one of the following, then you can calculate all of the parts of the triangle: -- length of the other leg -- length of the hypotenuse -- size of either acute angle
Providing it's a right angle triangle the formula is: hypotenuse2-base2 = height2
The side you use as the base does not matter. What does matter is that the height is the perpendicular distance between this side and the other vertex. If there is a right angle in the triangle, then use the two sides next to it as the base and height. Otherwise a bit of trigonometry will be required to work out the height of the triangle if it is not given.
I could solve this if I knew what kind of triangle this was. Equilateral, Right: 30, 60, 90?

It is impossible to find a triangle if only angle measures are given (all similar triangles have the same angles).
(base x height) / 2
You can either use a protractor or, if you're given the other angles in a triangle, you can subtract them from 180. An acute angle is an angle less that 90 degrees.
The given dimensions would not form a right angle triangle but in general the are of a triangle is 0.5*base*perpendicular height
