The area of a square floor on a scale drawing is 25 square centimeters, and the scale drawing is 1 centimeter: 6 ft. what is the area of the actual floor? what is the ratio of the area in the drawing to the actual area?

150 ft. and the ratio is 1/6

Step-by-step explanation:

So, because the scale drawing is in centimeters you have to change it into feet. 1 centimeter equals 6 feet, so you multiply 25 by 6. To find the ratio just make a fraction of 25/150 to get 1/6. So the scale drawing is 1/6 of the real floor.

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

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
