Question Help X 8.1.22
The vertices of AABC are A(-5,4), B(-2,5), and C(-2,2). If AABC is reflected across the line y = 1 to produce the image AA'B'C', find the coordinates of the vertex
B
The coordinates of B' after a reflection across the line y = 1 are (-2,-5).
(Type an ordered pair.)

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
