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°

Answer:

see explanation

Step-by-step explanation:

Note that cos315° = cos45° and sin315° = - sin45° and

cos45° = sin45° = $\frac{1}{\sqrt{2} }$ = $\frac{\sqrt{2} }{2}$

Hence

12(cos315° + isin315°)

= 12(cos45° - isin45°)

= 12( $\frac{\sqrt{2} }{2}$ - i $\frac{\sqrt{2} }{2}$ )

= 6 $\sqrt{2}$ - 6i $\sqrt{2}$
