Answers
1)
tan (a-b)=(tan a - tan b)/(1+tan a tan b)
15=45-30
tan 45°= (√2/2)/(√2/2)=1
tan 30°=(1/2)/(√3/2)=√3/3
tan (45°-30°)= (1-√3/3)/(1+1*√3/3)=(3-√3)/(3+√3)=(3-√3)²/6=2-√3
tan (-105°)=tan (75°)= tan (60°+15°)=(tan 60+tan15°)/(1-tan 60°*tan 15°)
tan 15°=2-√3
tan 60°=√3°
tan (-105°)=(√3+2-√3)/(1-√3*(2-√3))=2/(1-2√3+3)=1/(2-√3)=2+√3

Answer:
- 33.33%
Step-by-step explanation:
Given,
The number of books sold on January = 450,
While, the number of books sold on February = 300
Thus, the percent of change from January to February =
Second option is correct.
February : 300 books
the difference of Jan to Feb = 300 - 450 = -150
the percent of change = -150/450 x 100% = -33,3 %

Answer:
44.4
Step-by-step explanation:
it is a right angled triangle so
with reference angle x
perpendicular (p) = 7
hypotenuse (h) = 10
so Now
sin x = p/h
sin x = 7 / 10
x = sin^-1( 7/ 10)
x = 44.42°
Rounding to nearest tenth
= 44.4°
Answer:
7.1
Step-by-step explanation:
you use the Pythagorean theorem to solve this problem. a^2+b^2=c^2.
you are finding value of b plug the variables in = 7^2+b^2=10^2
=49+b^2=100
subtract 49 from both sides
b^2=51
Square root of 51 =7.141 round to nearest tenth =7.1
