In a group of 37 students, 9 study both Art and Biology. 6 study Biology but not Art.
9 study neither subject.
Given that a randomly selected student studies Art, what is the probability the student studies
Art and Biology?

14/39 or 35.9%

Step-by-step explanation:

We have a total of 39 students and 14 of which study both Art and Biology

and the rest of the total is unimportant to the question. Since there are 14 students out of 39 we can now do the math and figure out that 14 divied by 39 is right about 35.9 percent.

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
