Answer:
80
Step-by-step explanation:
To have 16 more pages means he has 20% more of the book to cover if he has already covered 80%
Let the number of pages in the book be X
20% of X = 16
20/ 100. * X = 16
1/ 5 * X = 16 >>> X = 16 * 5 = 80 pages.

Step-by-step explanation:
Apply triangle interior theorem,
Answer:
The answer to your question is:
a) sin Ф = -3/√10
b) cos Ф = 1/√10
c) tan Ф = -3
Step-by-step explanation:
See the picture below
just remember
sin Ф = opposite / hypotenuse
cos Ф = adjacent / hypotenuse
tan Ф = opposite / hypotenuse
The equation is of the form y = mx + c, where m is the slope and c just a constant. In this example, m=-5 and c=-2/3, so the slope is -5. The -2/3 is just a vertical offset and is irrelevant.
Answer:
(x,y)= (-6/5, -3)
