a reflection is a transformation that maps every point in △abc over a line, mn←→− , to △a′b′c′ so that and .

first blank: the intersection of BB′ and MN form a right angle

second blank: △ABC ≅ △A′B′C′

Step-by-step explanation:

The other options are incorrect because:

i think it would be 42cm

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
