Answer:
1/4x - 3 = 12
Step-by-step explanation:
When it says "three fewer," it means subtract three from one fourth of x. "Is" always means the equal sign. Knowing this, we get the equation:
1/4x - 3 = 12

Answer:
   (i) x° = 28°
   (ii) y° = 104°
   (iii) z° = 76°
Step-by-step explanation:
x° is an alternate interior angle where transversal PQ crosses the parallel lines, so it has the same measure as the one marked 28°.
   x° = 28°
__
The base angles of isosceles triangle PQR are both z°, so we must have ...
   z° +z° +28° = 180° . . . . . . . . . sum of angles in a triangle
   z° = (180° -28°)/2 = 152°/2 . . . solve for z
   z° = 76°
__
y° and z° are a linear pair, so ...
   y° = 180° -76°
   y° = 104°
