The isosceles triangle is a scale drawing of a flag. The perimeter of the actual flag is 22 in. Draw
another scale drawing of the flag with a perimeter
of 11 in. What is the scale of your drawing? Explain.

Scale factor =

Step-by-step explanation:

Perimeter of the actual flag = 22 in.

Perimeter of the scale drawing of the flag = 11 in.

Since, perimeter of a triangle = Sum of all three sides of the given triangle

Therefore, scale factor of the drawing

= =

=

=

Therefore, scale factor of the drawing will be .                                        

Each side of the scaled triangle will be half of the actual triangle.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
