Find the Area of shaded region, please give step by step explanation and answer fast pls

22cm²

Step-by-step explanation:

radius of smaller circle= 7/2=3.5cm

area of smaller circle=π×3.5=11cm²

area of bigger circle=π×10.5(radius is 7 plus 3.5)=33cm²

area of shaded area=33-11=22cm²

idk man good luck man

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
