Which point results when the point (−100, −100) is rotated 180° around the point (100, 100)? A) (200, 200) B) (300, 300) C) (−200, −200) D) (−300, −300) E) None of these.

A

Step-by-step explanation:

-100 -100, rotated by 180 would be the opposite, 100 100

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

b
