The builder of a parking garage wants to build a ramp at an angle of 10°10° that covers a horizontal span of 7575 feet. how long will the actual ramp be? round your solution to four decimal places.

The angle at which builder builds a ramp is 10 degrees

The horizontal span is 75 feet.

When we draw, we get a right angled triangle with its adjacent side as 75 feet and we have to calculate the length of the ramp which is the hypotenuse. Let us assume this to be "x" . Please refer to the attached figure.

Now, we know that the cosine of an angle = adjacent side/hypotenuse side

cos 10 = 75/x

x = 75/cos 10

x = 75/0.984807753

x = 76.1570 Feet

The actual ramp will be 76.1570 Feet

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
