2/3 hour . 1 hour = 60 minutes.
2/3 hour = (2/3) * 60
= 40 minutes.
20 pages took (2/3) hour = 40 minutes.
20 pages took her 40 minutes to read.
1 page = 40/20 = 2 minutes.
1 page took her 2 minutes to read.
For the angle A we have:
tan (A) = C.O / C.A
tan (A) = 10/24
Simplifying we have:
tan (A) = 5/12
For angle B we have:
tan (B) = C.O / C.A
tan (B) = 24/10
Simplifying we have:
tan (B) = 12/5
Answer:
The tangent of angles A and B is given by:
tan (A) = 5/12
tan (B) = 12/5
The answer is C.50. That is the answer.
