Salome’s salary increased from sh. 4000 to sh. 5000. Calculate the percentage increase of her salary

The increasse in salary = 25%

Step-by-step explanation:

% increase = (new value - original value) / original × 100 %

                   = (5000 - 4000) / 4000 × 100 %

                   = 1000/4000 × 100 %

                   = 0.25 × 100 %

                   = 25 %

Thus, the increasse in salary = 25%

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
