The answer will depend on what you know - and in what form.
If it is a triangle and
- you know the other two angles, it is simply 180 minus the sum of those angles.
- you know the length of two sides and an angle, you can use the sine rule.
- you know the length of three sides, you can use the cosine rule.
If you know the equations of the two lines, you can use the dot product of their direction vectors (plus a few simple steps).
Failing all that, you can use a protractor and measure the angle!

How do you find an acute angle?
To find an acute angle you need to find out if it is less than 90 degrees.
Where would you find a acute angle?
3 names of where you would find an acute angle is: Triangle, cone and a star.
How do you find sides of right triangle given only the hypotenuse and all angles?
One is the hypotenuse times the sine of one acute angle, the other, the hypotenuse times the sine of the other acute angle (or the cosine of the first).
Where would you find the shape of an acute angle?
An acute triangle
What type of polygon must have angles that each measure 108?
Assuming that you mean the inside angle is 108 the answer is a pentagon. Each angle inside the polygon forms an acute angle on the outside with the next side. The measurement of the exterior acute angle is: 180 - 108 = 72 . Since all the acute angle around the outside must add up to 360 we find: 360 / 72 = 5 There are five acute angles and therefore five sides to the polygon.
