Answer:
1. 16
2. 0
Step-by-step explanation:
order of operations
anything divded by zero is zero
Sinα=h/w
w=h/sinα, we are told that h=15 ft and α=70° so
w=15/sin70° ft
w≈15.96 ft (to nearest hundredth of a foot)

Answer:

Step-by-step explanation:
We want to write the conjugate of the complex number:

Recall that the conjugate of a complex number in the form <em>a</em> + <em>b</em>i is <em>a</em> - <em>b</em>i, and vice versa.
We can rewrite our complex number as:

Hence, <em>a</em> = 0 and <em>b</em> = 6.
Then its conjugate will be:
