2 answers:
Answer:
There are 50 pages in the book.
Step-by-step explanation:
Given that:
Martin has read 40% of the book.
Remaining percent = (100 - 40)% = 60%
Number of pages left to finish = 30
Let,
x be the total number of pages in the book.
60% of x = 30
0.6x = 30
Dividing both sides by 0.6
Hence,
There are 50 pages in the book.

Step-by-step explanation:
We require to find the third side of the triangle.
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x represent the third side, then
x² + 15² = 17², that is
x² + 225 = 289 ( subtract 225 from both sides )
x² = 64 ( take the square root of both sides )
x = = 8
Thus
tanΘ = =
cosΘ = =
sinΘ = =
cscΘ = =
