17.5 = x
Step-by-step explanation:
1st you add 85 and 55 since those to angles are congruent (means similar) to 8x
2nd you get 140 after adding then
3rd since the angles are congruent you just divide the 140 by 8 to get the value of x
Answer:
C

Answer:
18 minutes
Step-by-step explanation:
5 mins = 10 pages
10 mins = 20 pages
15 mins = 30 pages
20 mins = 40 pages
Just keep adding 5 to the minutes and 10 to the pages. then if you divide 10 by 5 (10÷5) you get 2.
2 is the amount of pages you read in 1 minute.
so 1 minute = 2 pages
Since you only need to read 36 pages, you know that it would at least take you 15 mintes to read 30.
then you start adding 1 minute until you get to 36 pages.
15 minutes = 30 pages
16 minutes = 32 pages
17 minutes = 34 pages
18 minutes = 36 pages
Therefore, it should take 18 minutes to read all 36 pages.
(A shorter way of doing this would be doing 10÷5=2, then just dividing 36 by 2 (36÷2) and you would get 18 which would be the minutes it would take you to read all 36 pages if you read at 2 pages per minute.)

For this case, we can model the problem as a rectangle triangle.
We know:
Height of the triangle.
Base of the triangle.
We want to know, angle between the hypotenuse and the base of the triangle.
For this, we use the following trigonometric relationship:

Clearing the angle we have:
