Two numbers add up to 247 and the first is 27 bigger than the second. what are the two numbers?

x + y = 247  

x + (x + 27) = 247  

x + y = 247  

2x +27 = 247  

x + y = 247  

2x = 247 - 27 or 227  

x + y = 247  

2x = 220  

x + y = 247  

x = 110  

110 + y = 247  

y = 137  

110 + 137 = 237

step-by-step explanation:

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
