The worlds longest suspension bridge is the akashi kaikyo bridge in japan. the bridge is 3910 m long and is constructed of steel. how much longer is the bridge on a warm summer day (30.0 °c) than on a cold winter day (-5.00 °c)?

1.642 m

Step-by-step explanation:

Given

Initial Length of bridge

temperature on cold day

temperature on hot day

Change in temperature is

Coefficient of linear expansion of steel

and length after change in temperature is given by

i have no clue at all sorry

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
