A wind turbine that ERCOT operates (even though it doesn't work in freezing weather when we REALLY need it) uses guy wires for support. In the figure, AC = 15 ft, ∡ABC = 60°, ∡ADC = 45°, and ∡AEC = 30°. AB =

AD =

AE =

Height of the turbine (EC) =

idk

step-by-step explanation:

maybe try   if it is work from a book, if not try

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

i'm not really sure how to answer that
