The graph below shows p, the number of
pages remaining in her book, after a nights.

The number of nights that she reads her book is 23

Step-by-step explanation:

According to the graph there are 156 pages and the slope shows she reads approximately 6.67 pages a night.

156 / 6.67 = 23. 3 = 23

goog may be able to you find that answer

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
