Please help me please i really really need help please

Step-by-step explanation:

If it obeys the Pythagorean theorem, it's a right triangle

     a² + b² = c²

 9² + 16² ?=? 25²

81 + 256 ?=? 625

       337 ?=? 625   NOPE not a right 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
