New price of gold is $1666 per ounce.

Step-by-step explanation:

Given that,

Old price of gold = $980 per ounce

Percentage increase in gold price = 70%

New price of gold = 1.7 * 980

New price of gold = $1666 per ounce

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
