Let's go through each problem to find the missing interior and exterior angles of the given polygons. I will solve them step-by-step:

### Problem 1:
For a quadrilateral, the sum of interior angles is \(360^\circ\).

Given angles: \(84^\circ, 121^\circ,\) and \(100^\circ\).

To find the missing interior angle (\(x\)):
\[
x = 360^\circ - (84^\circ + 121^\circ + 100^\circ) = 360^\circ - 305^\circ = 55^\circ.
\]

The exterior angle, which is supplementary to the interior angle of \(121^\circ\), is:
\[
x' = 180^\circ - 121^\circ = 59^\circ.
\]

### Problem 2:
For a triangle, the sum of interior angles is \(180^\circ\).

Given angles: \(120^\circ\) and \(50^\circ\).

To find the missing angle (\(x\)):
\[
x = 180^\circ - (120^\circ + 50^\circ) = 180^\circ - 170^\circ = 10^\circ.
\]

### Problem 3:
For a quadrilateral, the sum of interior angles is \(360^\circ\).

Given angles: \(95^\circ, 70^\circ,\) and \(x^\circ\).

The missing interior angle (\(x\)):
\[
x = 360^\circ - (95^\circ + 70^\circ + 80^\circ) = 360^\circ - 245^\circ = 115^\circ.
\]

### Problem 4:
For a pentagon, the sum of interior angles is \(540^\circ\).

Given angles: \(70^\circ, 110^\circ, 100^\circ, 105^\circ,\) and \(95^\circ\).

The missing interior angle (\(x\)):
\[
x = 540^\circ - (70^\circ + 110^\circ + 100^\circ + 95^\circ) = 540^\circ - 380^\circ = 160^\circ.
\]

The remaining problems are more or less similar to these examples. If you have any questions or want more details on specific problems, let me know!
