The angle of elevation to the top of a skyscraper is measured to be 2 degrees from a point on the ground 1 mile from the building. how tall is the skyscraper?

0.034921 miles or 1843774 feet tall

Step-by-step explanation:

Using trigonometric functions we know that and where =angle and r is the hypotenuse of the triangle.

First we will calculate the hypotenuse using the x equation, since we know x = 1 mile (distance from the building on the ground) we have:

Now we will calculate the height of the building using the y equation and so:

The building is 0.034921 miles or approximately 184.3774 feet tall.

4 + 5 7/9= 9 7/9

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
