How many feet are there in 45 yards 2 feet?
There are 3 feet in one yard. Therefore, 45 yards 2 feet is equal to (45 x 3) + 2 = 137 feet.
What is the tangent of a 45 degree angle?
It is equal to 1 (one). A 45 degree angle produces a vertical rise equal to the horizontal run, producing an isosceles right triangle with a hypotenuse of (sq rt 2)*a where a is the height/side. Opposite over adjacent = a/a = 1.
