Answer:
n = 6
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
2n = 12 ( divide both sides by 2 )
n = 6
Answer 10x
so the question doesn’t state the number of pages in these 10 books so i guess the answer would be 10x not a lot of info is given
The angle adjacent to angle 3 = 45 The figure is a kite and the long diagonal cuts the top angle in 2 Therefore < 3 = 45 degrees.
3(y+10) = 3(3). For additional simplification, the answer may be written as
y+10 = 3
