180 minus two known angles = unknown angle

If there is no length for the hypotenuse you have to use the Pythagorean Theorem. If there are two sides missing and a reference angle you could use Trigonometry.

Since the sum of the internal angles of a plane triangle is 180 degrees, the measure of the missing angle is 65 degrees. 180 - 74 - 41 = 65 degrees.

You can use various properties of angles to find the measure of the second angle. For example, if you can see that the two angles form a right angle, then you know they add up to 90°, so you can subtract the known measure from 90° to find the measure of the other.

That will depend on the shape but if it's a triangle then the missing angle is 54 because there are 180 degrees in a triangle.

Supplementary angles are two angles that measure up to 180 degrees. EXAMPLE: If the an angle measures 70 degrees, to find the missing angle, you subtract 70 from 180 because supplementary angles equal 180 degrees. Your answer (in this case 110) is the answer for the measure of the missing angle.

180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.

The missing angle measure is 100 degrees.

Subtract the two known angles from 180 degrees will give you the missing angle

If you are trying to find the missing angle of a triangle you do 180 degrees minus your two other angles. However if you are trying to find the missing angle of a quadrilaterals you do the same thing but with 360 degrees.

180 minus two known angles = unknown angle

It depends on what information you do have. There are different solutions depending on whether you have two sides and the included angle, or two sides and a median, two sides and an altitude, etc.

70 degrees

90 degress :P
