Thomas received $50 for his birthday. a week later, thomas spent $20 of his birthday money on a game. how much birthday money remained after he bought the game.

There would be $30 left after he buys the game.

Step-by-step explanation:

To find this, subtract the amount he spent from the amount that he had.

$50 - $20 = $30.

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
