Use the law of sine
note that:
sin(42)/4.8=sin(80)/PQ
PQ=4.8sin(80)/sin(42)
PQ≈7.1
note that:
sin(42)/4.8=sin(80)/PQ
PQ=4.8sin(80)/sin(42)
PQ≈7.1

Answer:
p=50t
Step-by-step explanation:
The more pages Crystal has to read, the more time she spends reading.
Let p=number of pages read
t=time spent reading the number of pages
As t increases, p increases.
This is a direct proportion and we can write it as:
Substitution of k into p=tk gives:
p=50t
Therefore, an equation representing the relationship between the number of pages Crystal reads and how much time she spends reading is:
p=50t
