Answer:
b)
x=65+32 [ being ext. angle of triangle is equal to the sum of two opposite interior angle]
therefore x=97°
Answer:
= - 12 + 316 i
Step-by-step explanation:
Given that -
z = 3 + i
<em>
=
</em>
<em>
= 9 +
+ 6 i</em>
<em>
= 9 - 1 + 6 i</em>
= 8 + 6 i
<em>
=
× z</em>
<em>
= ( 8 + 6 i ) × ( 3 + i )</em>
<em>
= 24 + 8 i + 18 i + 6 i²</em>
<em>
= 24 + 26 i - 6</em>
= 18 + 26 i
=
× 
<em>
= ( 8 + 6 i ) × ( 18 + 26 i )</em>
<em>
= 144 + 208 i + 108 i + 156 i²</em>
<em>
= 144 + 316 i -156</em>
= - 12 + 316 i
