Evan has a summer job to pick berries on a farm.

• he earns $2.00 every 15 minutes that he picks strawberries.
• he earns $2.40 for every 15 minutes that he picks blueberries.
• he picked strawberries for an hour and blueberries for 45 minutes.

15•3= 45, 2•3=6

15•4= 60, 2.40•4=9.6

This answer is $15.60

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

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
