From a point on the ground 62 feet from the foot of a statute, the angle of elevation of the top of the statue is 37degress. Fin
denpristay [2]
A right triangle is formed with the base of 62 ft and the adjacent angle is 37°. Using the definition of the trig function tangent, the height can be solved:
 tan 37 = h/62
h = 62 tan 37
h = 47 ft

Therefore, the height of the statue is 47 ft.

A rectangular scoreboard at a football filed has an area of 56 square yards.the scoreboard has a height of 4 yeatds. What is the
monitta
Alright so it's a rectangle so we know that both lengths are equal to each other and both widths are equal to each other. We know that the area, which is length times width, equals 56 and we also know that the height is 4 yards. So what times 4 equals 56? Calculate 56/4 and you will get 14. The height is 4 yards and the length is 14 yards. You're not done yet though! The question is looking for the perimeter, which is the total of all four sides. Since both lengths and both widths are equal, you would need to do 14+14+4+4. This equals 36 yards. Therefore the perimeter is 36 yards.
