90 degrees
Construct the angle.
There are at least two ways to find 1/4 of an angle. One is to measure the angle with a protractor and divide by 4. The other is to use Euclid's straight-edge-and-compass construction for the bisector of the angle. This gives half the angle. Then use the same construction again on the half angle to get one fourth of the original angle.
That isn't possible. complementary angles form 90 degrees or a right angle
you can measure a angle with a protracte.
If measure angle 3 = x2 + 4x and measure angle 5 = 3x + 72, find the possible measures of angle 3 and angle 5

Yes
You can but there are two possible solutions.

Yes, but the third side will also have to be 4 cm.If you ask: is it possible to construct a triangle with an angle of 60°and only 2 equal sides but not three, that answer is 'no'.
It is called a semi protractor and the fully-circular one is called an angle measurer

In a quadrilateral, three of the angles are obtuse. Which of the following could not be the angle measure of the fourth angle? 60° 90° 40° 20°
Yes. First draw a perpendicular (90 degrees) and then bisect the angle.
