The horizontal distance between the base of the skyscraper to the ship is 1145 feet.
Data;
- Angle = 45 degree
- Observation deck (adjacent) = 1145 ft
- horizontal distance (opposite) = x
<h3>Trigonometric Ratios</h3>
Using trigonometric ratios, we have the value of adjacent and angle, we can easily use tangent of the angle to find the horizontal distance

Substitute the values into the equation and solve

I believe the answer should be graph J
The factors of 100 are 1, 2, 4, 5, 10, 20, 25 50 and 100
the factors of 73 are 1 and 73. 73 os a prime number
These are what I call the Two Tired Triangles of Trig, 30/60/90 and 45/45/90. If you learn these cold now you'll save yourself some hassle down the road. These are generally the only right triangles teachers use when they want 'exact' answers.
Here are the facts to remember:
The ratio of the sides of the 45/45/90 triangle are 1:1:√2
The ratio of the sides of the 30/60/90 triangle are 1:√3:2, with the smallest opposite the 30 degree angle.
OK, let's fill in the angles first. Where we have a right triangle with 30/60/90 we fill in the missing one. For the half squares, the acute angles are 45 degrees.
For the lengths we apply the ratios. Hypotenuse of 45 degree right triangle is 4, so sides are 4/√2 = 2√2. When that's opposite 30 degrees, the other two sides are 2√2×√3 = 2√6 and 2×2√2=4√2.
2√6 is one side of a square, so all sides. The diagonal is 2√6×√2=2√12=4√3.
Half the square side is the smallest leg of a 30/60/90, so √6, with other leg √6×√3=√18=3√2 and hypotenuse 2√6.
