Answer:
.
Step-by-step explanation:
Answer:
x = 129
y = 82
Step-by-step explanation:
x + 51 = 180
x = 180 - 51
x = 129
y + 51 + 47 = 180
y = 98 - 180
y = 82

Answer:
x = 77, y = 63
Step-by-step explanation:
x - 5 = 72 ( corresponding angles )
x = 77
The 3 angles on the straight line sum to 180°, that is
x - 5 + 51 + y - 6 = 180, that is
72 + 51 + y - 6 = 180
117 + y = 180 ( subtract 117 from both sides )
y = 63
Given the equation:

We will find the value of (y) when ( x = 2i )
Note: i² = -1
so, when x = 2i

Simplifying the answer
So,

So, the answer will be y = -8+2i
